Mpa Pistol 9mm 4.5" 17-Round Threaded Barrel Pistol

The MasterPiece Arms MPA Pistol 9mm with 4.5" threaded barrel delivers a compact, mission-ready platform for civilian shooters, law enforcement, and military personnel seeking a reliable semi-automatic handgun. This 17-round capacity pistol bridges the gap between concealed carry ergonomics and tactical versatility, making it an excellent choice for duty use, home defense, or sport shooting applications. The threaded barrel design accommodates sound suppressors, giving operators the flexibility to configure the platform for their specific operational requirements or training environment.

Built by MasterPiece Arms with a 4.5-inch barrel, this 9mm pistol achieves a balance of sight radius, velocity, and overall maneuverability—critical factors in close-quarters defensive scenarios. The 1/2x28 threaded muzzle allows direct attachment of suppressors or muzzle devices without adapters, streamlining the platform for tactical customization. At 0.69 lbs unloaded, the lightweight profile reduces shooter fatigue during extended training sessions or duty carry, while the 17-round magazine capacity maximizes firepower without excessive bulk. The compact overall dimensions make this handgun suitable for inside-the-waistband or appendix carry while maintaining acceptable ergonomics and draw speed.

This MPA pistol is ideal for shooters who demand suppressor-ready capability and high magazine capacity in a carry-sized platform. Law enforcement agencies and military units evaluating cost-effective, modern 9mm options will find this firearm compatible with standard holster systems and red-dot optic mounting solutions. Before purchase, verify local and federal regulations regarding threaded barrels and suppressor legality in your jurisdiction. All transfers must be processed through a licensed firearms dealer (FFL) with proper background checks and waiting periods as required by applicable law.
