The G45 brings Glock’s crossover concept to 9mm with a compact-length slide on a full-size frame. This Gen5 frame has no finger grooves, features an RTF texture for a secure grasp, and includes a flared magwell to speed reloads. Front and rear slide serrations aid manipulation, and the Glock accessory rail supports compatible lights or other rail-mounted accessories.
Its 4.02 in Glock Marksman Barrel uses polygonal rifling and is paired with fixed iron sights. The pistol is striker-fired and finished in black. Capacity is 17+1 with the included factory 17-round magazines.
An Aimpoint ACRO P-2 3.5 MOA red dot is installed as part of this package. The ACRO P-2 is an enclosed-emitter optic with an aluminum housing, a constant-on runtime of up to 50,000 hours, and a CR2032 battery. This setup offers a durable, duty-grade red dot solution with a crisp 3.5 MOA aiming point.
Origin and markings are well-documented: the barrel hood bears the CIP N and Austrian AT shield proofs, and the frame is marked MADE IN AUSTRIA • GLOCK, INC., SMYRNA, GA. The barrel, slide, and frame have matching serial numbers, providing consistency across major components.
