The G45’s crossover configuration delivers a compact slide atop a full-size frame for a 17+1 capacity in a duty-sized grip. The Gen5 frame deletes finger grooves and adds RTF texturing and front strap checkering, while the Modular Backstrap System allows grip size customization. Ambidextrous slide stop levers and a reversible magazine release support left- and right-handed operation.
The MOS slide arrives with the cover plate installed and includes forward and rear serrations for confident manipulation. The slide wears Glock’s black nDLC finish. Fixed steel sights are installed, with MH3 markings on the sight set.
The 4.02-inch Glock Marksman Barrel contributes to the pistol’s accuracy potential, and the Safe Action system provides Glock’s familiar, consistent trigger feel. An accessory rail on the dust cover accepts compatible lights or other rail-mounted equipment.
Factory markings include "MADE IN AUSTRIA" and "GLOCK, INC., SMYRNA, GA," along with the noted U.S. patent reference. The barrel, slide, and frame carry matching serial numbers, aligning with Glock’s typical factory configuration.
