The G43X belongs to Glock’s Slimline series and is sized for compact carry while retaining a 10+1 capacity. It features a black polymer frame with micro-dot texturing for a secure hold and a black slide with both front and rear serrations for positive manipulation. The reversible magazine release and Glock Safe Action system are standard.
The 3.41 in steel Glock Marksman Barrel uses polygonal rifling, noted here as part of the GMB feature set. This barrel, combined with the clean bore condition, reflects careful prior handling.
An Aimpoint COA enclosed-emitter red dot is mounted directly into a slide cut behind the ejection port, with no adapter plate. The optic uses a red dot reticle and is marked 'Aimpoint COA.'
Factory markings include a slide roll mark reading 'GLOCK 43X USA 9x19' and a frame mark stating 'MADE IN USA GLOCK, INC., SMYRNA, GA.' The pistol retains Glock polymer iron sights with a polymer front blade and dovetailed rear notch. Matching serial numbers appear on the frame, slide, and barrel.
