ATI MGSG9SIG Magazine Adapter 9mm Fits Sig 320 Black 3 Pack

The ATI MGSG9SIG magazine adapter is a drop-in accessory that lets shooters run full-size Sig Sauer P320 9mm magazines in compact or sub-compact P320 grip frames. The adapter slides down over the magazine body and creates a flush, extended outline so the longer magazine seats properly and the pistol grip profile feels natural in the hand.

Built for 9mm Luger P320-pattern magazines, this adapter is a simple drop-in solution for owners who want to standardize on one magazine type across multiple P320 frame sizes instead of buying separate compact and full-size magazines. The black finish blends with factory magazine color, and installation is as easy as sliding the adapter onto the magazine before insertion - no tools required.

This listing includes a 3-pack of adapters, giving you spares for multiple magazines or multiple pistols. The MGSG9SIG is designed specifically for the Sig 320 platform and is not intended for other firearm models.
