Best Sig MPX Upgrades: From Good to Great

The Sig Sauer MPX Pistol is a 9mm pistol that can be customized and is easy to use. It is reliable, accurate, and easy to handle, making it a good choice for both defensive and competitive shooting.

This pistol has a short-stroke gas piston system that lowers recoil and a design that works for both lefties and righties. It also has a Picatinny rail system for mounting accessories.

The Sig Sauer MPX Pistol is a great gun right out of the box, but it can be made even better with improvements.

Adding a red dot sight can make it easier to find your target when you have to shoot quickly, and replacing the stock trigger with an aftermarket one can improve accuracy and feel. By upgrading the barrel, precision and consistency can be improved even more, especially at longer ranges.

In short, the Sig Sauer MPX Pistol has several popular upgrades that can make it work better, based on your needs and preferences. You may rely on me to have the best upgrades for this gun. Let’s do this.

Sig MPX Trigger Upgrade

First, I’d like to talk about how the Sig MPX rifle’s trigger could be made better. When it comes to updating the trigger, there are a few good reasons to do so.

Upgrading the trigger can make your shots much more accurate and precise as a whole. A trigger pull that is smoother and more consistent can help you stay on target and make it less likely that you will jerk or flinch while shooting. .

I have a suggestion for your trigger upgrade.

1. Timney Triggers SIG MPX Single Stage Drop-In Trigger

Timney Triggers SIG MPX Single Stage Drop-In Trigger

I think the trigger is a great way to upgrade the trigger. This trigger is the latest in a long line of semi-automatic replacement triggers made by Timney. They worked directly with SIG on its design and features, so you can be sure it’s great.

Heated and treated steel is used for the trigger, hammer, and bridge, and the body is made of anodized 6061 T6 alloy that has been machined. The trigger is also made of steel that has been heated and covered with black oxide, which makes it strong and long-lasting.

One of the best things about this trigger is that it comes with everything you need to put it in your gun. You won’t have to do any fitting, tuning, or gunsmithing to get it to work. It also has a straight blade, which makes it easier and more comfortable to hold.

The single-stage trigger has a fixed trigger pull weight of 4.5 pounds, which makes the trigger pull very smooth and clear. Once you take off the original trigger, installation is easy, and you can use the factory hammer and trigger pins.

Sig MPX Grip Upgrade

There is always the opportunity of having personal comfort over the factory trigger, even though the factory grip that comes with the Sig PCC is fairly nice and does the job.

Despite this, there is always the possibility of having personal comfort over the factory grip. And I am not an exception to this rule either. When considering other factors, the comfort of the grip is always given priority.

Because of this, I prefer to use the Magpul Pistol Grip in place of the grip that came with my MPX. In this manner, I will have a greater degree of control over the rifle. If you are interested in upgrading the grip that you currently use, I will suggest that you purchase this item.

1. Magpul Pistol Grip MOE K2 Plus AR-15 Rubber

Magpul Pistol MOE K2 Plus AR-15 Rubber Grip

Even in less-than-ideal conditions, this hold is intended to provide you with the maximum amount of control over the weapon you are using. Magpul Industries, which is well-known for producing high-quality rifle accessories and parts, is the manufacturer of this item.

The reinforced polymer body composition of the grip makes it robust and durable, while the comfortable wrap-around rubber overmolding makes the grip more secure and improves the user’s overall control. When shooting in wet or slick conditions, this is an especially important consideration.

Since the angle of the grip is optimized for use on PDW (Personal Defence Weapon) configurations, it is ideal for use on your MPX Pistol due to its more vertical orientation. This more acute angle enhances the shooter’s comfort and control when using short LOP (length of pull) rifles because it brings the shooter’s primary hand closer to their body.

Additionally, the one-of-a-kind design of the backstrap ensures correct trigger finger placement, which contributes to an overall improvement in accuracy and precision.

Sig MPX Brace

A brace is an attachment that goes on the back of your pistol and helps keep the gun steady while you shoot. Upgrading to a brace that is more comfortable and stable can improve your shooting experience by letting you better distribute your weight, improve your aim, and give you more ways to customize it.

With an updated brace, you can get more support and flexibility by changing the length or angle of the brace to fit your shooting style. Overall, upgrading your brace is an easy and inexpensive way to improve how well you shoot and get more accurate shots.

Let’s upgrade your brace with Sig Sauer SBX Folding Stabilizing Brace Sig MPX, MCX.

1. Sig Sauer SBX Folding Stabilizing Brace

Sig Sauer SBX Folding Stabilizing Brace

The brace can make your MPX Pistol much more stable and easy to handle. The brace gives you a solid, comfortable place to brace your wrist, which can help reduce recoil and make your shots more accurate.

It can also make your MPX Pistol more comfortable to use. The brace can help spread the weight of the gun more evenly across your arm, making it easier and more comfortable to hold for long amounts of time.

The brace is easy to connect and remove from your MPX Pistol, and it folds up into a small package that is easy to store and carry. If you wish to use your MPX Pistol with or without the brace, this is a good option.

Sig MPX Iron Sights

If you were seeking a disadvantage of this rifle, it would have to be the lack of a fixed sight that comes standard with this type. Those shooters who want to use iron sights for target practice will profit significantly from upgrading to separate iron sights for their pistol carbine, as this will be a fantastic addition to their weapon.

When it comes to iron sights for your MPX carbine, the Magpul flip-up iron sights are one of the best solutions on the market. This is also what I have on my rifle, so it all makes sense.

1. Magpul Industries USA MBUS Front & Rear Flip-Up Backup Sight

Magpul Industries USA MBUS Front & Rear Flip Up Backup Sight

The Magpul sight is made of a polymer that can take a hit. This makes it strong enough to use in harsh settings and during operations. Good news for everyone who wants to make sure their gun accessories can handle heavy use without breaking down or getting hurt.

The spring-loaded flip-up sight is easy to use because it can be opened from either side or by pressing on the top of the back sight. This allows you to move your gun quickly and easily, even when you are under a lot of stress.

Plus, the lock and spring pressure keep the sight standing up no matter what, so it won’t move around or get in the way.

The front sight is fixed, which is also a great feature because it gives you the right alignment for the A2 sight. The Magpul sight has the same height-over-bore as normal A2 irons, so you’ll be able to see your target clearly and hit it more accurately.

Sig MPX Red Dots

The red dot on your Sig Sauer MPX Pistol should be upgraded, man. It will make a big difference in how you aim and how accurate you are.

In general, a red dot sight is much faster and easier to use than standard iron sights. It helps you aim faster by putting a little dot on the target. It will also come in handy if you ever need to defend yourself or compete in a shooting event.

I like to use red dots because they are light, last longer, and are easier to see at night. So, I have two great red dot suggestions for your Sig MPX PCC that will help you see your target better and hit it more accurately.

1. EOTech HWS EXPS2 Holographic 1 MOA Green Dot Sight

EOTECH EXPS2 Holographic Weapon Sight

The Sight is one of the best hologram sights on the market right now. The 1 MOA green dot circle is very accurate and makes it 6 times easier to see when it’s bright out. And the fact that it’s green makes it even better for sunny days.

It also has a 68 MOA ring that makes it easy and quick to find a target. And because you can change the brightness, you can use it in any lighting situation.

Plus, it is made to be small and easy to use with a side button. This makes it easy to use with other magnifiers or optical devices and takes up little room on the rail. With the adjustable locking QD lever, it’s easy to connect it to your Sig MPX and use it together with the iron sights.

Last but not least, the EOTech HWS EXPS2 comes with a 10-year limited protection, so you know you’re buying a good product that will last a long time.

2. Trijicon MRO 2.0 MOA Adjustable Green Dot Scope

Trijicon MRO 2.0 MOA Adjustable Green Dot Scope

This camera is the real deal, and if you’re a hunter, you’ll love the features it has. First, it has a 2 MOA dot sight, which is great for shooting from far away. This sight improves aim, so you won’t miss.

The green dot reticle is one thing that makes this scope stand out. It is easy to see in forest, grassland, and tropical settings. This means that you’ll be able to find your prey more easily and shoot with more trust. And with this scope’s clear lens, you won’t miss a thing.

This Trijicon sight is also great because it comes with 6 different ways to place it. Trijicon has what you need, whether you want a full co-witness with a QD lever or 13 co-witness with low mounts. This means you can set up your camera however you like and take pictures from any point.

Sig MPX Weapon Light

If you want to take your Sig Sauer MPX Pistol to the next level, you might want to think about getting a weapon light. With a tactical light, you can shine light into even the darkest spots and make sure your targets are easy to see at any time of day.

Also, it will make you feel better when you need to defend your home because You can see and watch your surroundings.

1. Streamlight ProTac HL X 1000 Lumen Dual Fuel Tactical Flashlight

Streamlight ProTac HL X 1000 Lumen Dual Fuel Tactical Flashlight

I really think you should get a Streamlight ProTac HL X 1000 Lumen Dual Fuel Tactical Flashlight. As a shooter, you need a reliable, good-quality torch to keep you safe and help you find games.

The best torch for your MPX Pistol is the Streamlight ProTac HL X. It has a brightness of 1000 lumens, which means it can light up things up to 360 yards away. With this kind of power, you’ll be able to find your prey easily even when it’s dark, and make sure you always get a clear shot.

The fact that this torch saves energy is one of the aspects of it that appeals to me the most. It is made to last longer on a single charge than other lights.

The aluminum housing and anodized finish of the Streamlight ProTac HL X Flashlight makes it very sturdy and resistant to wear and tear. It also has an IP68 rating, which means it can withstand dust and water up to 2 meters deep.

This light has a tactical tail cap switch that lets you turn it on and off quickly or keep it on all the time, three different programs that you can choose from, and a pocket clip for ease. It comes with CR123A cells but can also be used with Streamlight’s SL-B26 rechargeable system and batteries, which are sold separately.

Sig Sauer MPX Compensator

Even though the Sig MPX is made to hold 9mm pistol ammo, you still need a good muzzle device. If you put a muzzle device on your Pistol Calibre Carbine, the gun will have very little recoil. So, updating your recoil control system will be good for you.

Since you can change the barrel on your MPX, I think the Sig Sauer 9mm 8″ Barrel would go great with the compensator I’m going to suggest.

1. Next Level Armament Sig MPX 9mm Speed Brake

Next Level Armament Sig MPX 9mm Speed Brake

The MPX Pistol is already known for having less recoil, but this speed brake/compensator will take it to the next level. Trust me, you’ll be able to shoot for longer without getting tired or feeling any pain.

It has a body made of stainless steel, which is strong and will last for a long time. It also has a Nitride QPD surface finish, which means it can handle high temperatures and won’t rust easily.

The device screws onto the M13.5x1H threaded barrels, which are popular on Pistol Caliber Carbines for the 9mm cartridge that looks like AR15s. This means that it will be easy to put on your Sig MPX Pistol.

The best thing about this speed brake/compensator is that it keeps your target in sight and stops the barrel from rising. This lets you hit your target more accurately.

Sig MPX Charging Handle

The Sig MPX is an AR-based pistol that has everything you need and more. Everything about this PCC is beautiful, even the smallest things. My only issue is about the quality of the charging handle, which comes with the package. Because the grip is so small, it is much harder to turn the scale when you are wearing gloves. Also, people who shoot with their left hand are not helped.

Because of this, the charging handle of your gun should be made stronger. Also, if you shoot with your left hand, you’ll need to switch out the stock charging handle for a customized one.

1. Radian Weapons Raptor LT Ambidextrous Charging Handle

Radian Weapons Raptor LT Ambidextrous Charging Handle

This is something you should definitely think about getting. I’ll explain why.

As a shooter, you know that when you’re out in the field, every second counts. So, the Raptor LT Charging Handle is what you need. With its reliable and easy-to-use design, you can charge your gun quickly and easily, so you’re always ready to take that perfect shot.

The longevity of this charging handle is one of its best features. Because the body is made of MIL-SPEC III hard-anodized 7075 aluminum, it can take strong hits and be used a lot. The surface is made of fiberglass-reinforced polymer, which makes it light and easy to use for long amounts of time.

Also, it is made to be used by both left-handed and right-handed shooters, so it can be used by either hand. The release buttons are easy to find and use, even in low light or when your hands are wet, cold, or covered with gloves.

Sig MPX Sling

I suggest that you upgrade the sling on your Sig Sauer MPX Pistol so that it is more comfortable, easy to use, stable, and accurate. A good sling spreads the weight out evenly, making it easier to carry for longer amounts of time and helping to keep the shooter in a stable position so they can be more accurate.

A well-made sling can also be adjusted quickly and easily to fit your body and give you different ways to carry your gun. This makes it easier to carry and store your gun in crowded or tight places.

1. Ferro Concepts Slingster – Modular Padded 2-Point Weapon Sling

Ferro Concepts Slingster - Modular Padded 2 Point Weapon Sling

One of the best things about the Ferro Concepts Slingster is that the pad is adjustable, which makes it more comfortable and less tiring to shoot for long periods.

The rubberized pull tab is another cool feature. It makes it easy and quick to make changes, so your pistol can go from being safely slung to ready for battle in no time. This is a must-have for hunters like us who need to move quickly and efficiently in the field.

And let’s not forget the custom injection-molded pull tab that comes with a custom-welded steel common loop. This makes it very easy to connect the sling to your gun, which is especially important for competition shooters who need to be able to quickly switch from one gun to another.

Sig MPX Magazine Upgrade

Last but not least, I’d like to suggest a change to the magazines of the Sig PCC so that it can be used in competition shooting. A longer clip will give you more time between shots, which will help you hit your target more often. Your MPX pistol will also work better if it has a good magazine release and magazine coupler.

1. Sig Sauer MPX 9mm 30-Round Magazine

Sig Sauer MPX 9mm 30-Round Magazine

Let me explain why this magazine upgrade is a game-changer for any outdoor task. First of all, the larger magazine means you won’t be reloading as frequently, giving you more time to focus on your shooting targets. The 30-round capacity is great for long tasks where you need a lot of rounds.

The revolutionary design of the gas piston means you won’t feel any extra pressure. This makes it easier to stay on target and take those follow-up shots without being thrown off. Plus, the ribbed holding surface of the magazine and the strong polymer follower make it easy to hold onto your gun.

The Lancer System MPX Magazine Coupler makes it easy for this magazine to work with your current factory magazine. This is another great thing about it. So, you can use both clips at the same time to get even more rounds.

I also suggest the Odin Works Extended Magazine Release if you want to take your magazine game to the next level. This lets you change the magazine quickly and easily without stopping your shooting routine. This lets you keep your attention on your targets and get the most out of your hunting experience.


In closing, the Sig MPX Pistol Caliber Carbine is an excellent firearm that possesses all of the essential characteristics of an AR. On the other hand, you won’t need to lug the tag and the list of drawbacks associated with using AR pistols around with you. This cutting-edge firearm provides you the flexibility to play around with different aspects of your shooting technique.

Sig MPX will always have your back, regardless of whether you want to utilize it for a competition or while you are in a defensive stance. However, some necessary upgrades should be made to this pistol carbine before you take it to the competition field.

I have already provided you with a list of all of the essential upgrades for this pistol so that you won’t have to bother about listing all of these accessories. You need only look through them and select the ones that are relevant to your MPX submachine.
