No reviews have been written for this product.

Description

This is a Glock 21 Gen4 in .45 Auto with Glock Night Sights (GNS), shown with its factory clamshell case. The Gen4 frame brings the improved RTF texture and reversible mag release, delivering a confident grip and easy controls on a proven, soft-shooting .45 platform. The case label indicates a 5.5 lb trigger.

Condition appears very good used with light cosmetic marks on the slide (see photos). Bore looks sharp in the muzzle shot, and the luminous GNS are intact. This full-size .45 is ideal for home protection, range sessions, or duty-grade reliability with big-bore punch.
