The Defender series keeps the proven closed-bolt, straight-blowback action while integrating a 4-slot Picatinny rail at the 6 o’clock position for lights or lasers. A QD sling mount at the rear receiver adds carry versatility.
The 4.5-inch barrel is threaded 1/2x28 and ships with MPA’s tubular thread extension, giving buyers an easy path to add a suppressor or compensator. Adjustable post front and flip-style rear aperture sights provide a clear, modular sight picture.
A top-mounted charging handle and paddle-style magazine release maintain the classic Defender ergonomics. Feeding from a 30-round polymer magazine, the pistol offers substantial on-board capacity in a compact, full-size format.
The upper receiver is machined from 4140 steel for strength, while the lower is 6061-T6 aluminum finished in black Cerakote to cut weight compared with earlier all-steel versions. Decal Grip panels deliver a secure purchase without adding bulk.
Made entirely in the USA, the MPA30T brings collectible MAC-family heritage and modern manufacturing in a ready-to-accessorize platform.
