This MPA 9mm pistol is based on the 30SST, but includes a fully machined aluminum pistol grip. The grip is MPA's most ergonomically designed grip system incorporating a "Solidworks" designed profile allowing the use of standard Glock-style magazines, low profile magazine release, and Decal Grip grip panels. The pistol also includes additional upgraded features such as adjustable front and rear sights, L-Bracket with QD Sling plate. This is also a multi-caliber pistol. Utilizing a change of the bolt and barrel, the firearm can be modified to fire 40 cal & 357 Sig. With a bolt, barrel and pistol grip change, the 30DMG will fire 5.7x28mm.
