Our Single Piece Magazine Release is now available in a Macro configuration! Designed as a true extended magazine release for macro frames, this magazine release utilizes our innovative retention design eliminating the factory plastic catch and adds a knurled button extension of .080" (2mm) over an OEM Macro mag release for better reach and faster mag changes without breaking down your grip. Catch side is profiled for a flush look to OEM macro frames and any aftermarket frames that follow the macro profile on the trigger guard and magazine release area - see below for fitment info.
Made right here in the USA from 17-4 Stainless Steel and coated in black DLC for a long service life.
Sold as a complete kit including:
- MPI Single Piece Macro Magazine Release
- ISMI stainless steel spring
- Two black oxide coated stainless steel set screws (1 for a spare)
- Allen wrench for install
- Install Instructions

GRIP MODULE/FRAME FITMENT
If your current grip module uses the extended plastic catch with the extra flap of plastic covering the back of the release this is the one for you
Confirmed flush fit on the catch side on the following frames:
- Sig Macro
- Icarus Air Polymer
- Wilson Combat Macro ONLY (XL and other Wilson frames require our Standard Mag Release)
- Mischief Machine Alpha Gen 3/Commander Gen 2 (Original Commander and others require our Standard Mag Release)
SIG SAUER AXG GRIP MODULE FITMENT
Our Macro version is an excellent upgrade for the AXG for those wanting an extended mag release. Please note, the Macro version will stick out past the side of the grip module as shown below. OEM Macro plastic catch shown for comparison, our fitment is designed to replicate the OEM fitment.

Stop thinking about it and just get one!
If you're still thinking about it, I'm tellin you, get it! LOL I've got 10 of these extended mag releases in my P365s. No accidental mag releases within the holster nor while shooting. The beauty of not having to shift your grip to drop a mag is priceless. Super fast mag swaps, no fear of the mag release falling apart because of a plastic retainer. Simplicity and ease of install as well as super easy uninstall. Get it, you won't regret it. Seth I'm gonna need another 3 pretty soon! Going for a bakers dozen! hahaha

7 Builds...7 MPI Mag Releases.
Well my last review was on September 26th, 2025, bought another mag release for a third P365 Radian build. And I said I would more than likely be buying another 2-3. I lied, I've since bought another 4 and I still have five more builds to go after this. I'm going for a Bakers Dozen in P365s! LMAO I wonder if MPI has a "Subscribe and Save" program? LOL I just love the fact that I don't have to shift my grip at all to hit the mag release. Anyway, if you've been thinking about getting one of these mag releases, just get it, you won't regret it.

"Kinda meh..."
...is definitely NOT how I would describe MPI mag release! This is a quality built piece and I have run about 3k rounds (mix of SPEER LAWMAN TMJ 147/124/115gr) through my Legion with no issues. Every one of my eight P365 builds have the MPI Sinlge Piece Ext Mag Release installed. When I bought my ECM R11 Macro and R11 FUSE, the grip module came with the MPI mag release installed! Win/Win! Great product, great price, so-so owner. LOL Kidding! Seth is an awesome dude and his Customer Service skills are beyond reproach! I am happy to continue to support MPI, thank you Seth!!

Masks Magazine release
I am just getting into the P365 platform and decided to build one around the FCU using all aftermarket components. Ran across the Maskas Precision name in forums and of course some YouTube videos. The Maskas magazine release absolutely exceeded my expectation on fit and finish, functions perfectly in the Icarus ACE aluminum frame, and matches aesthetically with the frame. Would highly recommend to others looking for top quality parts.

MPI Macro extended mag release
Complete game changer for the P365 platform. Eliminates the subpar quality of the OEM mag release and replaces it with a super solid one piece design. Will be buying in the future for my other pistols.

Third Build Required a Third Mag Release!
What can I say? I absolutely love the Maskas Extended Mag Releases! Simple to install and I don't have to worry about it falling apart on me. I'll be purchasing at least another 2-3, since I have all these spare parts and everyone knows that it's a sin to have extra parts and not make a whole new build outta them.

P365 Mag Release
The notorious p365 mag release failure is old news. MPI did what we have all been thinking, design a single solid metal mag release with a ledge to engage without breaking your wrist.. I bought both standard and extended for my Juggernaut grip module. Bothe fit and function perfectly, but the extended is flush and perfect with the holster. Thanks and wishing you much success. I see everyone with a Sig is already offering the solution. KM

The BEST Mag Release Bar None!
This is the second one I bought for another P365 X Macro build that I'm in the process of putting together. The first one was for my 365 Legion and I also bought one for my P320. SUPER easy to install! It took me longer to take the OEM one out! Literally took less than a minute to install. The quality is 100% and I continually recommend this mag release to everyone I come across that has a P365. Since these are part of my EDC rotations, the last thing I want is for the OEM mag release to fall apart on me if I'm in a defensive situation. This was a no brainer purchase and as I build other P365s rest assured that I will be installing the Maskas Mag Releases! I'm excited to see what else Maskas puts out for the P365 and perhaps the P22X series!! Thank you Maskas for the quality of your products!

AXG Mag Release, Saved by Seth from Maskas Precision!
TL:DR, AXG Mag release sucks, Seth came through in the clutch! Got the AXG grip module for my P365 XMacro TacOps on Saturday. Put 200 rounds through it on Sunday. Shot a match on Tuesday, and during the 4th stage, the magazine hung up when I went to reload... Take it over to the safety table to see what's up, and the magazine release SPRUNG out of the AXG module. The catch dropped, spring shot off into the woods, and I was SOL. Have a match coming up on Sunday (five days from when the ACG Mag Release decided to quit), and didn't want to go back to my Macro TacOps grip module.... Did research on replacement mag releases, and all of them needed the damn spring that disappeared. I kept searching for a replacement mag release that came with the spring. Enter Maskas Precision... I took a flyer and called the number. A human answered (Seth), and I explained my situation. He got a one-piece replacement out that afternoon, and it arrived today. I'm 100% good to go for Sunday's match Thank you, Seth ?? Their YouTube video is excellent, and the installation was a breeze. Took <5 minutes.
