Best Sig P365 Grip Modules [Hands-On Tested]

Since 2018, the Sig P365 has dominated the concealed carry market. It’s been one of the best-selling guns in the country and spawned an entirely new genre of firearms: the micro-compact.

At the core of every P365 sits a removable fire control unit (FCU). This removable device is the serialized portion of the gun and is considered the “firearm.”

This design makes it easy to remove, allowing you to swap grip modules, barrel lengths, and more.

Mix popularity with modularity, and you get a firearm that’s going to have a huge aftermarket. A significant portion of the aftermarket is dedicated to providing you with a new grip module.

As the owner of a P365 since 2018, I’ve put my gun through a lot. I shot the original so much that I ended up breaking the grip. After that, I went shopping for new grip modules, and I never really stopped.

With that in mind, let me introduce you to the five grip modules that have always stood out to me!

How We Chose the Best P365 Grip Modules

Between everyone here at Pew Pew Tactical, we have shot on just about every OEM grip that Sig offers for the P365. We used that knowledge as a baseline when looking at aftermarket grips.

But grips are an inherently subjective thing. Everybody has different hands, so comfort levels can, and will, vary between different people.

That being said, when we were looking for the best grip modules, we included a few other criteria in addition to just pure comfort.

Our picks for this list were based on the following: Overall feel, texture aggressiveness, ability to get a high shooting grip, construction material, accessory rail type, and overall feature set.

Best Sig P365 Grip Modules

1. Mirzon Hybrid Polymer Grip Module – Editor’s Pick

I love Mirzon’s approach to grip design. Their P320 grip module was effective in reducing recoil for me. So when Mirzon offered to send me the P365 grip module, I jumped at the opportunity.

Mirzon makes a grip module for the standard P365 and for the XL model. I went with the XL model, but the design between the two is similar enough that I’d recommend both.

The Mirzon Grip Module revamps the P365 ergonomics. Key changes include an enhanced beavertail and an aggressive trigger guard undercut. One thing that’s tough to see, but easy to feel, is the grip’s design.

It’s somewhat round and shaped brilliantly to fit your hand. You don’t feel corners or edges; just a round grip that slips into your hand like it’s part of your hand. Then, with the beavertail and undercut trigger guard, you can slip up nice and high and get fantastic control over the gun.

Up front, we get a Picatinny rail. It’s perfect for most accessories, but this means many XL holsters won’t work. However, it will work with X-Macro holsters.

The Mirzon Grip Module also adds some seriously aggressive checkering. It’s well-suited for wet and sweaty hands and will lock the gun down and prevent it from rocking around when faced with the most +P of 9mm cartridges.

This grip module would be perfect if you’re rocking and rolling with the P365 for something like IDPA Back-Up Gun divisions. It captures that race gun feel. For non-competition use, it’s still well-suited for everyday carry and shooting.

At $99, it’s not the cheapest grip module, but the ergonomic improvement might be worth the cost to some shooters.

2. Tyrant CNC Snub Nose – Interchangeable Backstraps

Our first is the latest P365 grip module to fall into my hands. Tyrant CNC, as the name implies, is typically an all-metal company, but they went polymer.

The Snub Nose grip module came out swinging and went big, but also kept things small. Since that’s clear as mud, let’s explain it a little better.

The Tyrant CNC Snub Nose grip module gives you the X-Macro grip length for use with the Sig 17-round magazines.

However, the Snub Nose has a shorter dust cover that allows you to use the standard-length P365 slide, hence the Snub Nose name. You can also opt to put a longer XL or X-Macro slide on it if you wish.

The Tyrant CNC Snub Nose grip module features a fairly aggressive grip texture made up of a variety of lines flowing in different directions.

This grip also features a fairly interesting curve. The bottom of the grip rounds out quite far and pushes your hand up naturally. A high grip equals more control, and more control equals faster and more accurate shooting.

The Snub Nose grip module also has a huge rear beavertail and an undercut trigger guard. You can get both hands nice and high while being comfortable.

Speaking of comfort, the Tyrant CNC Snub Nose also accepts interchangeable backstraps, a first for the P365.

Tyrant CNC also includes their aggressively textured magazine release that feels slightly extended. At $80, it’s not the cheapest, but it gives you a fantastic grip module design with some excellent ergonomics.

3. Wilson Combat WCP365 Grip – Most Affordable

If you want an affordable upgrade for your P365 grip module, you can’t go wrong with Wilson Combat. Yes, Wilson Combat, makers of 1911s that cost several thousand dollars, make an affordable grip module. It comes in several configurations.

You can get the standard, XL, X, and X-Macro model grip modules. Among these designs, we even get Wilson Combat exclusive oddities, like the X-Macro short, which gives you an X-Macro grip length for a standard P365 slide (like the Snub Nose).

The WCP365 grip modules mostly maintain the same overall design as the original Sig-style grip modules. Wilson also uses the proprietary Sig rail on a lot of these grip modules, which makes them compatible with standard P365 holsters.

That’s a nice touch since we are looking at affordability and not trying to spend another $50 or more for holsters.

The WCP365 has a sunburst grip texture that looks and feels fantastic. It’s aggressive and well-placed, and it makes the gun look good. It might be my favorite grip texture, and leave it to a custom-1911 shop to make stuff that looks as good as it functions.

The grip module’s beavertail is about the same size as the X-Macro, which helps encourage a high grip.

A hidden feature of the WCP365 grips modules is a slot in the rear so you can add tungsten bars for weight. More weight means less recoil.

These grip modules can be found for less than $50 if you shop around, and they even come with the magazine release. Overall, it’s a tough value to beat.

4. Icarus Precision A.C.E. Grip Modules – Best Metal-Framed Grip Module

I’m partial to metal-frame striker-fired guns, and when Icarus released a P365 grip that was all metal and all awesome, I jumped on it.

I was an early adopter, a very early adopter. In fact, the example you see in these photos is no longer sold, but don’t fret—the Icarus Precision Grip Modules have only gotten better.

The A.C.E. series of metal grip modules makes things a little heavier but enhances ergonomics significantly. Icarus Precision makes options for all standard P365s, including X, XL, MACRO, and FUSE models. There is a little something for everyone.

First, the grip design has been reworked to allow for a more comfortable and higher grip. It has an aggressive beavertail that keeps your hand locked in as high as possible, along with an undercut on the trigger guard that allows you to get even higher without stretching your hand out.

The modern A.C.E. grip modules feature an extremely aggressive checkering. It sticks to your hand and makes sure recoil doesn’t make the gun twist or move in your hand. The frame is incredibly comfortable in the hand, despite the aggressive texture.

Icarus opted to use a standard Picatinny rail to make it easier to mount standard lights, lasers, and similar accessories. To accommodate the Picatinny rail, the grip module is slightly wider than a standard P365 grip module. This leads to our main downside.

You can’t use standard P365 holsters with your Icarus A.C.E. grip. However, the company does maintain a list of compatible holsters.

But if you can get past the holster hangup, the Icarus A.C.E. grip is all kinds of cool; it looks and feels fantastic and brings heavy(ish) metal to the grip module conversation.

5. Smith Defense S365 Grip Module – Most Modular

With Ozzy still in our hearts, let’s keep it metal. Our last grip module is my personal favorite—the S365 Grip Module from Smith Defense.

Part of the P365’s charm—dare I say its selling point—is the gun’s modularity. It’s why this article is being written.

But the S365 grip module brings that modularity to a completely different level. It’s a metal grip module that is also inherently modular itself.

You start with a base grip module, but you can then bolt on a standard or extended dust cover, or a standard or extended grip and grip panel.

This allows you to change your S365 grip from a standard-sized P365 grip to an XL-sized P365 grip. It’s a brilliant idea and an awesome grip module. You can also make a P365L config with a long slide and short grip, or vice-versa.

Even if this grip weren’t modular itself, it would still make this list. The design encourages a nice, high grip, and it also features aggressive texturing. The grip angle and design are very 1911-like, which some people may find preferable.

The dust cover features a standard Picatinny rail, so it’s capable of accepting all sorts of lights, lasers, and similar devices. This means that it doesn’t fit standard holsters.

It is also not compatible with the thumb safety versions of the P365.

My biggest gripe is that it doesn’t come with a magazine release. I hate paying for and installing magazine releases. It’s such a small part that they could include it with a $300 grip module.
