MasterPiece Arms MPA30K Defender 9mm 4.5" 30rd Pistol

The MPA30K Defender is a 9mm large format pistol built around an aluminum receiver with a Picatinny rail along the top. The 4.5" barrel is threaded at the muzzle, and the gun uses a side cocking handle instead of a rear charging setup, which leaves the optic rail clear from front to back. A side folding pistol tube sits at the rear of the receiver; no brace is fitted to it.

Controls come from an AR pattern fire control group, so the safety and the trigger fall where a carbine shooter already expects them. Magazine capacity is 30 rounds. The whole package stays short enough to live in a bag or behind a seat without the length of a long gun, and the threaded muzzle leaves the door open for a muzzle device or a suppressor down the road.
