The Glock 43X MOS w/ Radian Ramjet™ & Afterburner™ & Holosun 407K pairs Glock’s slimline 9mm platform with a compensated 3.90" barrel and a mounted Holosun 407K red dot, creating a compact pistol that is easy to control and quick to aim. The black slide, gray Radian Ramjet™ & Afterburner™ intra-compressor combo, and matching frame finish give this 15-round handgun a sleek, low-profile look while maintaining Glock’s familiar ergonomics. This direct-acting system is engineered to significantly reduce muzzle rise and felt recoil, allowing for exceptionally flat shooting and fast recovery between shots.

This model is well suited for concealed carry, home defense, and regular range practice thanks to its slim profile, manageable recoil, and clear red dot sight picture. The combination of the MOS-ready slide, Radian Ramjet™ & Afterburner™ system, and Holosun 407K optic offers fast follow-up shots and confident target acquisition. It is an appealing choice for shooters who appreciate Glock’s proven reliability and straightforward design combined with premium, match-grade performance upgrades.
