This MAPP1 MS follows the licensed CZ-75/Tanfoglio design, placing the slide rails inside the frame for a lower bore axis and smooth cycling. The pistol accepts standard CZ-75/Tanfoglio magazines, simplifying spares and upgrades.
The frame is molded from glass-fiber-reinforced polymer, trimming weight while retaining strength. Textured gripping surfaces on the sides, frontstrap, and backstrap promote a secure hold, and an external ring-style hammer allows easy visual status checks.
A matte black parkerized slide carries rear serrations for positive manipulation. Fixed white-dot sights are dovetailed front and rear for straightforward replacement or adjustment.
The installed 3.66" carbon-steel barrel is hard-chrome lined for corrosion resistance and extended service life. For users planning to run a suppressor or compensator, the included 4.4" threaded barrel installs with no gunsmithing required.
Short-recoil operation with a double-action/single-action trigger offers a long initial pull and crisp subsequent shots. A left-side manual thumb safety adds an extra layer of control.
