The MPA30T Defender uses a closed-bolt, hammer-fired blowback system for straightforward operation. The fixed 4.5 inch threaded barrel provides a stable barrel-to-frame interface, and the top-mounted charging handle complements the top-eject design for efficient cycling.
Construction pairs a steel upper receiver with an aluminum lower, all finished in Cerakote for added durability. A two-pin takedown/receiver system simplifies disassembly. The pistol includes a short Picatinny accessory rail at the forward lower-right of the receiver for light or accessory mounting.
Controls and sights are purpose-built: a manual rotary safety, fixed iron sights with protective ears front and rear, and a textured polymer grip with finger grooves for a secure hold. Capacity is stated at 30+1 rounds, and the pistol uses detachable MasterPiece Arms MPA-pattern 9mm magazines (not Glock).
Markings include the MPA Defender shield logo with Comer, GA 9MM designation. Made in the USA, this Defender is configured with features that align with the series, presented here in excellent condition with a mirror-bright bore.
