Secure grip — Wrap-around grip texture provides a confident hold without being harsh on the hand.
Slide design — Thinned profile at grasp points and directional serrations front rear and topside for fast positive manipulation under stress.
Barrel options — Match-grade conventionally rifled spiral-fluted barrel promotes reliable debris evacuation. Threaded-barrel models are available for states that allow muzzle devices.
Trigger — Drop-safe flat-faced aluminum trigger with a 4.5–5.0 lb pull and a crisp tactile reset.
