Mec-Gar Plus-2 Adapter Set for SIG P320 9mm Magazines - Black

The Mec-Gar Plus-2 Adapter Set is a drop-in DPS (Drop Protection System) base extension designed for SIG Sauer P320 full-size 9mm magazines. This replacement floorplate and inner base set increases magazine capacity by two additional rounds, giving P320 owners a simple, affordable way to add round count to their existing factory or Mec-Gar P320 magazines.

Mec-Gar is a well-known and respected manufacturer of high-quality pistol magazines and magazine components, and this Plus-2 adapter kit reflects that reputation for precision. The set includes a black polymer Plus-2 magazine extender paired with a phosphate steel locking plate that is heat-treated for long service life and a secure fit. The components install in place of the factory floorplate on compatible SIG Sauer P320 full-size 9mm factory magazines, as well as Mec-Gar's own SIG P320 DPS magazines, giving you a reliable capacity upgrade without buying entirely new magazines.

Finished in black to blend seamlessly with factory magazines, this Plus-2 adapter set is a straightforward upgrade for P320 shooters looking to add two rounds while retaining the proven reliability of their existing SIG or Mec-Gar P320 9mm full-size magazines.
