The Matador Arms MAT-9K Roller Pistol (brand part no. MATK-9HK-B/B) brings genuine roller-delayed operation to a modern, American-made 9mm large-format pistol that feeds from H&K MP5-pattern magazines. Matador Arms designs the roller-delayed system to reduce recoil, lighten the upper, and increase reliability over straight blowback, while the bufferless design frees the rear of the receiver for a 1913 rail interface. Ambidextrous upper and lower receivers, an ambi safety, an upgraded mil-spec trigger, and a non-reciprocating reversible charging handle keep the controls flexible for any shooter, all in Type 3 hard-anodized aluminum and backed by a lifetime warranty from this veteran-owned maker. A 30-round magazine comes included. Among large-format pistols, the MAT-9K favors shooters who want MP5-magazine roller-delayed shooting without the surplus price tag.

Frequently Asked Questions

What magazines does it use? H&K MP5-pattern magazines, and a 30-round magazine ships with the pistol.

Can I add a stock to the rear 1913 rail? As sold this is a pistol; attaching a shoulder stock to its 5.5-inch-barrel configuration creates a short-barreled rifle that requires approved NFA registration first. Folding brace-type accessories follow current ATF rules.

Is the charging handle reversible? Yes, it is non-reciprocating and can be set up on either side.
