Increase control, comfort, and confidence with the Pearce Grip PG365 Grip Extension, a purpose-built polymer magazine extension engineered to enhance handling of the SIG Sauer P365 when using 10-round magazines. With a textured black finish and a full 5/8" gripping surface, this low-profile extension gives shooters better purchase on the magazine without changing concealability or reliability — ideal for everyday carry, training, and defensive use.
Engineered for the SIG P365 — Fit You Can Rely On
The PG365 is precision-molded to mate perfectly with factory-style 10-round magazines for the SIG P365. Unlike bulky add-ons, Pearce Grip’s design preserves the firearm’s original footprint while adding a natural index point for your pinky or support-hand fingers.

Fitment & Compatibility Notes
Specifically engineered for SIG Sauer P365 factory-style 10-round magazines.
May not fit non-factory or heavily modified aftermarket baseplates or magazines with differing dimensions — always verify fit before relying on it in a defensive scenario.
Check holster clearance after installing the extension. Some ultra-tight concealment holsters may need slight adjustment or a magwell-compatible holster to maintain smooth draw and reholster.
Maintenance & Care
Wipe with a damp cloth to remove dirt or debris; mild soap if needed.
Avoid solvent-heavy cleaners which can degrade polymer over time.
Inspect periodically for cracks or loosening, especially after heavy use or drops.
