Detailed Description


Wilson Combat has reengineered the SIG-SAUER P365/P365XL grip frame to optimize its practical shooting and concealed carry potential.  These all-new molded polymer grip modules will enhance your grip and improve recoil control.  Our significant improvements in shape, texture, and overall ergonomics will give your P365 the superb feel of an expertly hand sculpted custom gun with a simple grip change. These six new models cover standard and XL P365 frames, with or without a manual safety in black and tan color.

Our fresh look at the P365 grip module incorporates the suggestions of tactical trainers, champion shooters, and firearms experts into the final product that has a look that is unmistakably “Wilson”.  We believe it is the most practical, comfortable, and stylish P365 grip available and the ideal choice for concealed carry and defensive handgun use.

Excellent product, minor personal refinement needed
I have put the 365X/XL module with tungsten weight on my EDC P365. Install was easy and straightforward. The change produced an improvement in controlled fire grouping and a significant improvement in rapid fire groupings. The magazine release being uninstalled was a non-issue, since I am lefty and would have to switch it anyway. The magazine release doesn’t fee quite as secure to install as the stock. The handgrip finish is a bit aggressive for many users. I used some light to moderate sanding in a few places. I found the front and rear finish to be too aggressive in the hand. In addition the back side finish and edge of the side finish was harsh enough to irritate when carrying concealed. The loose fitting tungsten was a hastle. The holes are not true and have a slight taper. So the tungsten is tighter as it goes in. Wrapped 1 wrap of electric tape and they are tight. 1 is tight enough it won’t ever come out…
Worth the price
Feels like how the gun was supposed to feel out of the box, takes minimal time to get used to and improves the ergo factor to a level that is extremely satisfying. The price is scary but unless you have a polymer mold in your garage this is definitely the better choice compared to the skinny little stock grip module.
Best upgrade hands down
First, thank you Wilson Combat for providing an exceptional upgrade at an exceptional price. I respect a company that provides a product worth more than they charge. I put this on my P365XL and the difference is unbelievable. The factory grip is too small for my medium size hands and the sandpaper like texture on the sides is hard on clothes and skin when carried IWB. The texture on these grip modules is perfect as far as I am concerned. This grip module fit like a glove, no problems and took a great gun to the next level. If you're considering getting one, do yourself a favor and go for it. If you are dissatisfied you're likely insatiable.
Excellent modification for Sig P365XL
This WC grip module is really well designed from the slightly rounder grip to the stipling that goes higher on the grip than on the Sig stock grip module. Along with the Tungsten weight kit added, this really gives the overall gun an additional 1.5 oz. of "heft" to counter felt recoil when shooting. The grip module was super easy to install the FCU into, and I had no trouble installing the mag release button after watching the install video. This is a well-designed and built modification that improves the P365XL into an even better pistol. Highly recommended!
Best 356XL Grip Module!!
Wow!! Took an excellent feeling gun and made it better than my wildest dreams could have imagined!! Unbelievably comfortable and the ergonomics are second to none. If you like you P365XL factory grip, you'll fall in love again once you install the WC grip module. 10 stars if I could!!!!
P365XL awesome upgrade
I bought this on a hope it would give me a better grip. This grip is just a bit bigger forward to aft. Which helps a ton with trigger pull and recoil. It is also a bit fatter which helps with recoil. The grip doesn’t change holster fit at all. The only complaint I have with this grip module is they didn’t change the sub par rail on the front to picatinny this would have been a 6 star review with that upgrade.
Sig 365xl upgrade
Outstanding Glad I found you guys.
A fantastic addition to my P365X
I love the look and the overall feel of this grip. I think this is one heck of a bargain to be honest for $69. I was worried about it fitting my holsters. I have this on a P365X and I use a 508 holster and a Crossbreed holster, it fits both perfectly fine. The 508 still has a very solid click when inserting the gun. The 508 has the most solid click I have ever had on any holster btw. You can't go wrong with this grip in my opinion. A little tip. When putting in the magazine release button, you have to push it an hold then insert the lock piece on other side. I was expecting it to slide straight through without pushing. I hope that makes sense. It's easy once you figure that out. It's overall a very easy install.
Excellent upgrade
This an excellent upgrade to a great gun. I thought the P365XL was just a bit small in circumference for me. The Wilson Combat grip module fixed the issue, perfectly. It's just right for me and the gun points even better. It is well worth the cost.
Looks good, feels good and can reach the magazine release better. It's Wilson Combat Excellence
Stellar Improvement
The installation process only took minutes! Once the new grip module and the p365x slide were mated, the first words out of my mouth were "Holy Guacamolies!" What a difference! The first trip to the range verified that sentiment. Better recoil mitigation and the natural feel in my hand, not to mention the great looks, together turned my favorite conceal carry handgun into my favorite gun altogether. Thank you, WC!
PITA to install magazine release
I love everything about this grip module, except for the fact it ships without the magazine release installed. I have arthritis and it took me 3 hours to get the magazine release installed. I was just about ready to send it back and order something different when I finally got it
Added to my P365X - Awesome Upgrade!
After a quick chat with a Wilson Combat technician, I decided to purchase the P365XL module for my P365X (not the XL). I have a WC P320 and I love the grip module. So naturally I wanted this for my P365. And this did not disappoint. The installation video was awesome and I was up and running in about 10 minutes. I did like the stock Sig Grip, but it was a little small. This WC module adds the perfect size. Also adds ease in transition from my WC P320 and now the P365X with the same style Grip Module. Highly Recommended! This has to be the best upgrade for the price....$65 - you cannot go wrong!
Exactly what I'd been waiting for for two years.
Just exactly the P365 grip I'd been waiting for. A little judicious sanding with emery cloth, of a couple of hot spots on the grip and beavertail to adjust the amount of bite on the front and back straps and good to go. Wilson should add more spec on the weight kit however. The Wilson Tungsten weight kit was not available at the time of my purchase. So I bought the standard sizer Armory Craft Tungsten weight kit instead. Having used that kit quite successfully in my WC Sig p320. The Standard Tungsten rods are way to long to allow the 365's fire control unit to seat. I had to have the rods cut down and cutting Tungsten is a pain in the behind. Once properly sized though...The Weight KIT is worth every extra penny. Wilson just needs to make the Weight Channel Spec a little more clearly stated on product page. The WC Unit is slightly thicker and I noted that I didn't really care for where my finger fell on the Factory Sig Flat Trigger. I tore my trigger group down and threw in one of the original Sig P365 curved triggers that I had laying around and found that I liked the conventional curved trigger, quite a bit better with the thicker WC grip module. Other than that slight bobble with the weight kit...At $64.00, It beats the snot out of the $200+ Icarus offerings.
Custom Fit & Feel
Everything I had hoped for from WC. Improved ergonomics, smoother magazine insertion, great texture and what I had hoped for most, improved fit between grip module and FCU. The fit is as it should be and WC knows this and it shows their attention to the details. Trying the TC rods next, I suspect if they did not improve the user interface WC wouldn’t market them. I see a WC P320 in my future.
WC Sig P365XL
This P365XL started out with the romeo zero (which really made me question Sig's integrity) dumped the zero (had to order the sight plate- really Sig?!!!) Added a Hogue slip on for it then the Lima365. Laser did not function well with the Hogue (used a dremel) but never really happy with this pistol... Until now - It finally came together - because this grip module makes it. If you have a 365 - get this grip module.
The P365 is a great platform but the grips are too small for me to get the consistent groupings I was after. I went from P365>P365XL>P365XL with aftermarket laser stippled grip module>P365XL with the Wilson Combat grip module. I finally hit the sweet spot. Night and day difference. If you have large hands save yourself the hassle I had… just buy these.
I love my p365x. From Sig i thought it was everything I could hope for. Then, Wilson announced this grip. I don’t know how to describe it but it took my best feeling micro compact and mare it that much better! Thank you Wilson Combat.
Could use a little palm swell
Very nice grip module with great width but could use a little grip swell at the rear. The stock Sig XL grip module has more swell at the rear. Otherwise a simple swap out.
Much Better Grip
The new Wilson grip module transforms the feel of the 365 XL. Much more natural in the hand. Best money I’ve spent in a while. Highly recommend to anyone who owns a 365 or 365 XL. Super easy to change out.
Awesome grip
I have Wilson Combat grips on all my AR’s, and like the design and texturing so much that I had to give this a shot on my 365x. It is super easy to install and only took about 2 minutes. This grip module is far superior to the Sig module, and the texture and fit in my hand is unbelievable. Shipping was fast, and Wilson Combat hit it out of the park with this one!
Exactly what I was hoping for
I just received the grip module in the mail today and immediately swapped over my P365 FCU. When ordering this grip module, I was hoping that the actual grip portion would be a more rounded shape when compared to the original SIG grip. I absolutely got what I was hoping for with this grip module. The grip portion itself fills the hand better than the original SIG grip that has flat sides. This grip module feels great in the hand. The grip texture on the front and back straps is great and has the aggressive texture to lock it into your hand, but only has the texture where you need it. The beaver tail is a great feature as well. And finally, my P365 now matches with my P320s that all have Wilson grip modules on them.
Love the texture, shape and size.
Initial impressions are good. I have never taken the FCU out of my 365, and the install was very simple. I am not sure if its just perceived or if I really do, but it feels like I get a higher purchase on the grip than the stock XL unit. The texture is great, the magazine release works like it should. I have very small hands, so grip sizing is always a concern for me, and this module feels great.
Made a great pistol better
The stock grip was great for concealing, but lacked in comfort to some degree. The side texture slides over fabric, but locks in when gripped firm. With just a little curve to fit the palm well.
P365XL Frame module
Wilsons service was awesome, and the frame module was shipped and received in a couple of days. this frame module with Wilsons grip size and texture gave this little Sig 365 a big gun feel and control. Good job Wilson!!
Prompt shipping. great fit, finish, and feel
