Matador Arms MAT9-K | 9mm Roller-Delayed | 5.5 in

The Matador Arms MAT9-K is a roller-delayed pistol chambered in 9mm Luger designed for reliable, controllable operation in a compact package. It features a 5.5-inch nitrided barrel, ambidextrous lower controls, a non-reciprocating reversible charging handle, and compatibility with Glock-style magazines. The MAT9-K ships with an A3 folding pistol brace and a 1913 rail for basic accessories. For an optic, consider a Trijicon MRO red-dot, which pairs well with this platform and stays under $1000.

Suggested uses include precision range training and competitive target shooting, where the roller-delayed system and ergonomic controls support follow-up shots and repeatable sighting.
