Pearce PG365X Grip Extension for SIG P365X/XL

The Pearce PG365X grip extension is a magazine base plate replacement engineered to improve control and ergonomics on your SIG P365X or P365XL. Designed for shooters who want a better grip purchase on an already compact platform, this accessory adds roughly half an inch of gripping surface to your 10- or 12-round magazines—without changing how many rounds they hold. If you've found the factory base plate too small for a solid grip, or you run the gun in appendix carry or backup role, the extra real estate makes a tangible difference when drawing or reloading under stress.

Built from high-impact polymer, the PG365X is engineered to survive hard use. The material incorporates a texture pattern that matches the frame of your P365X/XL, so it feels like a factory upgrade rather than an aftermarket add-on. Pearce backs the durability with drop-test validation across a wide temperature range—from deep cold (-20°F) to heat (250°F)—so you're covered whether you carry in Minnesota winters or Arizona summers.

Installation is straightforward: the extension simply replaces the magazine's base plate. No modifications to your magazines or firearm required. It's a no-fuss way to gain comfort and control on one of the most popular micro-compact 9mm platforms on the market.
