Product description
The Pearce Grip Grip Extension Sig P365 XL is a magazine base plate extension designed for increasing grip length on compatible Sig P365X and P365XL magazines. This magazine base plate replaces the factory floor plate to add approximately one half inch of grip surface without altering magazine capacity. The Pearce Grip Grip Extension features a black finish and polymer construction.
The extension is designed to fit factory 10 round and 12 round magazines for the P365X and P365XL platform while retaining all original internal components. It is constructed from high impact polymer to support repeated use and consistent handling. The added length provides a more defined grip interface for the user during firearm handling. In typical use, this magazine base plate extension is installed to extend the grip surface and assist with magazine identification while maintaining the original capacity and configuration.
