The MPA30T is a semi-automatic, simple blowback 9mm from the Defender series with the distinctive top-mounted round charging knob. The top-cocker layout keeps the charging handle centered and clear of the sides for straightforward manipulation.
Its 4.5 inch barrel is threaded 1/2x28 tpi and arrives with a cylindrical barrel extension installed. The short under-receiver Picatinny accessory rail (3-slot) provides space for a compact light or other compatible accessory.
Sights include a protected front post and a low-profile, adjustable rear notch, giving a clean sight picture with on-gun elevation and windage adjustment. The manual safety features the factory extension for positive engagement.
