Firearm and Magazine Compatibility

The P365 family includes several different sizes; confirm that you have the standard P365 configuration stated on this listing. Verify the firearm, optic, barrel and accessory configuration before checkout. The magazine carrier is intended for the compatible magazine family associated with the listed firearm. Extended baseplates, sleeves, aftermarket magazines and oversized floor plates can affect fit; contact us before ordering if your magazine is not in its original configuration.

Non-Light-Bearing Configuration

This product is not intended for a weapon-mounted light unless a light is specifically offered in the product options. Choose a dedicated light-bearing holster when a weapon light is installed.
