What is a Grip Module?
A grip module is basically what is referred to as the grip handle of the pistol. Without it, the pistol would be useless. Besides, how else are you going to use it when you cannot properly hold onto it? These modules can be added to the handle part of your pistol and are designed to provide you with excellent gripping ability.
Most shooters use these as upgrade accessories as opposed to using the grip that comes as a factory default on their P320 pistol. These modules come in three types: small, medium, and large. All three sizes have grips available in the usual full-size, carry, compact, and sub-compact sizes.
What Size of Grip Module Do I Need?
The short answer is: it depends. It will depend on the size of your pistol and the grip size itself. For example, if you have small hands and have a full-sized P320, you’ll need a small grip module that will be compatible with full-sized P320 pistols. To help you find the best possible size for you and your pistol, you can refer to the following chart here. It’s important to know the measurements of your pistol so you have a good idea of what module size you’ll need.
What Makes a Great Grip Module?
There are a few characteristics that make a great grip module stand out among the rest. It’s up to you to know what they are so you can distinguish between those that are considered flimsy and unreliable. Here’s what you need to look for:
Price
Granted it may not be a characteristic per se, however, a lot of budget shoppers are attracted to the price tag. They want something that’s affordable. While it’s understandable, no gun owner should simply settle for cheap. As a rule of thumb, find one that is excellent in quality but fits within your budget range. It’s not an impossible task and it will definitely save you the frustration of dealing with a cheap and flimsy grip module.
Material
It’s important to find out which materials are used for manufacturing a potential grip. For example, polymer is one material that can be found in grip modules. It is proven to be one of the best materials for its resistance to damage and abuse. At the same time, proper materials also lend themselves to the superior gripping ability.
Installation
A lot of new and seasoned users of grip modules won’t have a good amount of gunsmithing skills to utilize. So we looked for grip modules that would be easy to install. Imagine having a better grip on your pistol without having to rely on a gunsmith. Most of these will take a few minutes of your time with the right kind of tools. Why spend more money and waste time waiting when you can do it yourself?

Pros
Cons
What Recent Buyers Report
A lot of recent buyers were satisfied with the grip module overall. Most were able to install it and get a nice good hold on their pistols. One user said it was like holding onto flypaper while shooting. It also gave them more control and made shots more accurate.
What Recent Buyers Report
The design of this grip covers most of the lower half of the pistol. That makes installation a whole lot easier. Since it’s made from high-quality polymer it is expected to be one of the best in terms of longevity. It will definitely hold its own for years or decades, as long as you take great care of your pistol.
Who Will Use This Most
This grip module will be best used on almost any P320 pistol no matter which caliber it is. It will fit most pistols classified as full-size P320s. It will benefit a lot of concealed carry and even casual target shooters who want the best in grip and control. The boost in accuracy will be a major bonus here.
What Could Be Improved and Why
One possible improvement would be to make sure the edges themselves are smoothed before it ever hits the market. This way, it will fit better, rather than having to deal with edges that might snag on a holster and make drawing the pistol more difficult.
Bottom Line
This SIG Grip is perfect for most full-sized pistols of almost any caliber. It might be closer to a universal grip module as long as the pistol itself is in the “full-sized” category. Once installed, your pistol will be a little more rugged and your grip and control will be even better than before.
Runner-up:
Sig Sauer 320X SIG Medium Grip Module
Pros
Cons
What Recent Buyers Report
Most new buyers were able to install this with ease. Once they installed it, they said the grip was a bit better in quality than their previous factory default grip. One user remarked that it was able to fit his hand perfectly. Another reported that her small hands were able to handle the pistol just fine and continued to maintain control of her pistol.
What Recent Buyers Report
This grip module is perhaps one of the best for shooters with medium-sized hands. Surprisingly, it can also fit hand sizes that are slightly smaller. The grip is nice and sturdy and allows shooters to have a lot more stability over their pistol. They were able to shoot closer and in tighter groups when going through a full magazine.
Who Will Use This Most
If you’re a concealed carry kind of P320 owner, chances are you’ll benefit from this if you’re looking to add a little more stability while in the firing position. Target shooters and competitive shooters seem to like it, as well. It is perfect for when you want total control over your pistol.
What Could Be Improved and Why
While it might not be an urgent need, one improvement suggestion would be to reduce the overall size of the grip slightly so it won’t cause any bulging for those who intend to conceal carry on a daily basis, especially when wearing an IWB holster with the intent to make it as concealable as possible.
Bottom Line
If you’re looking for a pistol grip that will be great for full-sized pistols and perfectly fits average hands, the Sig Sauer 320X is the perfect grip that will fit most calibers and full-sized P320 pistols. You’ll be able to get a good grip on it no matter what your application is.
Best for the Money:
Sig Sauer Compact Small Grip Module
Pros
Cons
What Recent Buyers Report
This grip was a favorite for a lot of budget buyers, especially those looking for an excellent grip for their compact-size P320 pistol. One user said it doesn’t take up a lot of room and bulge up. He was able to maintain his level of concealability after upgrading his old grip module to this. The hold was solid and allowed users better control and increased accuracy.
What Recent Buyers Report
This pistol grip module is perfectly-sized for a P320, especially for the type of pistol most concealed carry practitioners rely on. Once installed, it will give you a better grip and a more rugged, all-around quality. The odds of this receiving damage from being accidentally banged around? None. That’s how tough this grip really is.
Who Will Use This Most
This will be used by compact P320 users across the board, especially those who carry their pistol on them for regular conceal carry purposes. It might also come in handy for those who have smaller hands and may not be able to handle mid-size or even large-size pistol modules.
What Could Be Improved and Why
While the fitting is the major con, there really isn’t any improvement suggestion we can think of. However, it would also be a good idea to include something to make it a sweeter deal for budget shoppers. Probably by including a couple of magazines in the mix. If there is one thing you might need extras of, it is magazines. Plus, they would fit perfectly in the mag well even after you’ve installed your new grip.
Bottom Line
If you’re looking for an excellent grip module that will fit most compact pistols without breaking the bank or compromising your concealability, the Sig Sauer Compact Small Grip Module might be exactly what you’re looking for. If you have small hands, you’ll know that no other grip comes close to this.
Best X Carry Grip Module:
Sig Sauer P320 X-Carry Grip Module
Pros
Cons
What Recent Buyers Report

What Recent Buyers Report
This grip is made mostly for concealed carry pistols like the P320. It’s at a fairly decent size where it won’t cause much bulging. It’s built to last and will give you an even firmer grip without you ever having to sacrifice any concealability.

What Could Be Improved and Why
This grip should be compatible with IWB carriers. While nobody with an OWB holster has an issue with it, those who decide to wear an IWB holster for better concealability shouldn't have to suffer any discomfort due to the size of the grip.
Bottom Line
If you conceal carry and need a grip that will be perfect for every day pistols, no grip module comes close to the Sig Sauer P320 X-Carry Grip Module. Add this onto your pistol and instantly be able to gain better control over your pistols.
Best Subcompact Grip Module:
Sig Sauer P320 Subcompact
Pros
Cons
What Recent Buyers Report
A lot of recent buyers were happy with this grip. They were able to easily fit this on their subcompact pistols. For the most part, they were able to maintain their concealability. One of them added that he was able to fit it in his inside-the-waistband holster just fine and it was still comfortable.
What Recent Buyers Report
Subcompact pistols are by far some of the best when it comes to concealability. Adding a grip to make it a lot better in terms of overall handling is perfect for those with small hands or for anyone who uses a pistol in a concealed carry application.
Who Will Use This Most
This grip will be best used by those looking to use their pistol for EDC purposes. At the same time, this module will be something that won’t compromise the concealability of your pistol. It’s also an install-it-and-forget-it kind of grip module. If you hate wasting time with complex installations, you’ll love this.
What Could Be Improved and Why
Despite no major cons, this grip module should be lumped in with a nice package deal for those looking for a subcompact grip module but on a budget and possibly can't afford a separate holster. Since this is excellent for EDC use, a holster thrown into the mix might be a nice idea.
Bottom Line
If you want a great, reliable grip for your subcompact P320 pistol, you’d be insane to pass up the opportunity to give this SIG Sauer Subcompact grip module a try. Just add it on and use it to your advantage, whether in a self-defense or target shooting application.
Best X5 Grip Module:
Sig Sauer Grip Module for P320 X5
Pros
Cons
What Recent Buyers Report
Most recent buyers were impressed with the grip module. It was easy to fit and had a solid feel to it. They were able to get a good hold so they could fire off an entire magazine at the range. Shooting groups were much tighter thanks to the added control advantage they got from this grip module.
What Recent Buyers Report
This grip module fits all available SIG P320 calibers. It makes it much sturdier once you install it, which takes only a few minutes. As an added bonus, it won’t slip out of your hands if you’re outdoors at the range and it suddenly starts to rain and it even works for most users who tend to have sweaty palms.
Who Will Use This Most
This grip module will likely be best used in a concealed carry application. It will get you through a lot of high-pressure situations and prevent you from dropping your pistol if your hands tend to sweat because of stress. Rest assured, you’ll still have a lot more control over it compared to your old factory grip.
What Could Be Improved and Why
Despite fitting onto most pistols, it should be designed to be compatible with most magazines. Yes, it can work with all P320 pistols across all calibers but why won’t it accept all kinds of different calibers when it comes to magazines?
Bottom Line
If you’re looking for a great grip module that might be the closest you can get to a universal-type, the P320 X5 Grip Module might be something worth investing in. Easy to install, easy to grip, and easy to control, this grip module is exactly what it should be. It is also reliable, allows better control, and best of all, provides a perfect shooting experience.
Aspects to Consider Before Buying
Aside from the basic characteristics and qualities, you should consider additional aspects that will factor into your purchasing decision. This way, you’ll know exactly which grip will be best for you, rather than choosing one at complete random. Here’s what you need to consider:
What Size Are My Hands?
First and foremost, not all grips are created equal. They are made for various hand sizes and are not a one-size-fits-all thing. Pay close attention to the measurement of your hands so you know which size grip to choose for your pistol.
Is my Pistol a Full-Size, Compact, Etc.?
Another size to pay close attention to is that of your pistol. If you have a full-size pistol, obviously you’re going to need a grip module that will perfectly fit full-size models. These modules will be measured to fit the pistol you’ve got. A full-sized grip module will be too big for a compact pistol or smaller and vice versa.
Which Caliber is my Pistol?
The P320 comes in various calibers. Keep in mind that most grips are basically fit to handle all of them. So regardless of the caliber your pistol is chambered in, a good pistol grip will work to your advantage in any application. There are a few exceptions, though, so be sure to check for compatibility before clicking the "buy" button.
Conclusion
If you’re looking for the best SIG P320 grip module, be sure to find one that will fit both your pistol and your hand size. Once you find one that fits you perfectly, there is nothing that will stop you from having excellent control over your pistol and also better accuracy. This accessory is one of the most important ones to have on your pistol, so it is advantageous to find one that is a better upgrade to your factory default grip.
