GLOCK 43X Blackout #2 – Optics Ready, Sub-Compact 9mm, Cerakote, Zaffiri Threaded Barrel, Suppressor Sights
The GLOCK 43X Blackout #2 delivers tactical performance and concealment in a custom subcompact platform. Chambered in 9mm, this striker-fired, semi-automatic pistol features a 3.41" match-grade GLOCK Marksman Barrel plus a Zaffiri 1/2x28 threaded barrel, ready for suppressor or compensator use. Shark Coast Tactical’s hybrid stippled polymer frame—without finger grooves—ensures secure handling under stress, while front serrations and a Cerakote black finish complete a premium, rugged look.
This model is optics-ready, accepting RMSc and RMSc-footprint optics only (must use included SCT screws to mount). Suppressor-height sights provide clear sight picture with or without optics. The slim grip, built-in beavertail, and reversible magazine catch contribute ergonomic comfort and ambidextrous usability. Two 10-round magazines are included, supporting both range training and concealed carry applications.
