The Icarus ACE 365 311 SL is a slimline frame that takes the P365 platform and gives it refined ergonomics without adding bulk. Built from aerospace-grade aluminum, this left-handed grip module merges the proven SIG P365 compact size with 1911 double-stack grip geometry so you get full-size control in a carry-friendly profile.
What sets the 311 SL apart is its slim design. It keeps the concealability that makes the P365 popular while improving how the gun sits in your hand. The slim 1911DS-inspired grip shape includes a subtle memory hump in the backstrap, which helps your hand settle into the same position every time you draw. That consistency matters for accuracy and followup shots. The aggressive 360-degree texturing on all sides keeps your grip secure through the draw and recoil.
This frame is built specifically for left-handed operators with thumb ledge placement designed around your natural hand orientation. The flared magwell guides reloads efficiently, and the double-undercut trigger guard lets you get your hand higher on the frame for better control. A 17-4 stainless recoil lug system with double set screw locking provides solid slide interface support. The integrated accessory rail lets you mount compatible lights if your setup needs it.
The 311 SL accepts Macro 17 and 21 round magazines, giving you flexibility with capacity without changing frames. It works with P365 XL or Macro-length slides, and pairs with standard P365 3.1-inch slides when you run a compatible flush-fit compensator (PMM and Radian are the only flush-fit options that work cleanly). The frame accepts your existing P365 Fire Control Unit without modification, so building is straightforward. Keep in mind this requires an ACE 311-specific holster for proper fit and retention.
Yes, the 311 SL accepts your factory P365 Fire Control Unit without any modification needed. It's compatible with P365 XL and Macro-length slides, as well as standard P365 slides paired with flush-fit compensators like PMM or Radian models. You'll need macro length magazines (17 or 21 round) and should plan on getting an ACE 311-specific holster since the slim profile requires proper fitment.
The 311 SL is purpose-built with left-hand thumb ledge placement and the slim profile makes manipulation easier for lefty operations. It also has aggressive 360-degree texturing that gives you solid grip security, a memory hump for consistent hand placement, and a flared magwell that helps with reload speed. Compared to standard frames, it gives you ergonomics designed around how you actually shoot.
Yes, it's specifically designed to be a slimline frame that doesn't add width to your carry gun. It combines full-size 1911DS grip ergonomics with the P365's compact footprint, so you get better control than factory without the bulk. The slim profile balances shootability with concealability, making it a solid choice if you want control without printing.
No, the 311 SL requires an ACE 311-specific holster because of its unique profile and dimensions. Standard P365 holsters won't fit properly. Make sure you have a compatible holster lined up before or at the same time you install this frame to make sure your carry setup is ready to go.
