Glock 43X, 9mm. Threaded barrel with a Suarez Comp to make it same size as the G48 (G48 holster comes with it). It's sporting a 3D printed magwell that has held up well and a Streamlight TLR-6. It does have night sights and an aftermarket trigger that's really nice. Has the factory parts in the box, I bought the Shield Arms 15rd mags for it and an ext for one of them. Neo Mag is included for carrying the spare mag. Factory barrel has about 50round through it and the one currently in the blaster has about 350. Call or text 865   839   7024
