The X-Grip Magazine Adapter for Sig Sauer P320/250SC lets you run full-capacity P320/250C magazines in your subcompact P320/250SC, turning a single-stack carry gun into a higher-capacity platform without sacrificing the compact form factor you chose.

Magazine adapters are a practical way to maximize versatility in the Sig P320 ecosystem. The X-Grip design lets you use the larger magazine supply you may already have while maintaining the ergonomics and concealability of your subcompact. Whether you're looking to extend range trips or keep a spare magazine type in your loadout, this adapter solves the compatibility puzzle.

The black finish matches standard Sig P320 aesthetics, and the secure fit ensures the magazine seats reliably in your grip. Installation is straightforward—no gunsmithing required—making it an accessible upgrade for P320/250SC owners who want more rounds on board.
