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

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.

    Peace of mind!

    I was in the process of spec'ing a 365 AXG Legion build and I kept reading reviews of the OEM Mag Release falling apart on it after low round counts. Since this build was going into my EDC rotation, I was not willing to take a chance of it failing on me if I happened to be in a defensive situation. Everyone was talking about MASKAS so I bought one and I am glad I did! One piece, all metal. It was a no brainer! The simplicity of installation was a "chefs kiss". I'm going to building out another 365 and will be ordering another Extended Mag Release! Stop thinking about it and do it, you won't regret it!

    WAY Better Than Expected

    Posted by R. Gordon on May 22nd 2025

    I had just purchased a P365 Fuse and while switching grip modules, the magazine release catch retainer plastic just...snapped. I was already planning on using M*Carbo's extended mag release, but the weakness of that plastic led me to find this. And WOW. Tactile, solid, ergonomic (for me). I did use a stiffened stainless steel spring, just for the extra "bump" and corrosion protection, but I'm sure that's a negligible difference. It just feels...good. Sig should have made this type of installation their OEM mag release instead of relying on a paper-thin piece of plastic to hold a critical component together.

    Posted by Sean on Apr 14th 2025

    Love this product, Maskas took the one downside to the 365 series pistols and developed not only a fix to the issue but a revolutionary solution. The installation was easy ( thanks to the provided YouTube video) the quality of the part is great and the shipping was fast. Love this company. ABSOLUTELY BUY THIS FOR YOUR 365!!!!
