Special Features

• Crossover platform pairs the G17 full-size frame with the G19 compact slide, giving the Glock G45 Gen6 (U64550203) a shorter nose profile than the G17 while maintaining a full firing grip and 17-round standard capacity.
• RTF6 dual-pattern grip texture covers the frame with an aggressive yet comfortable surface that locks the pistol in place under heavy use, wet conditions, and extended range sessions without requiring grip tape or aftermarket stippling.
• Gen6 frame removes finger grooves from the grip, opening the pistol to a wider range of hand sizes and allowing a more natural point of aim for shooters whose fingers did not align with previous Glock groove patterns.
• Integrated palm swell, undercut trigger guard, and fixed enlarged beavertail work together to push the hand higher on the grip and create a more secure, consistent hold across all shooting positions.
• Factory optics-ready slide uses a modern direct-mount plate system engineered for Gen6, with three included plates covering the most widely used red dot footprints so you can mount your preferred optic immediately.
• Flat-faced trigger provides consistent finger placement across the trigger face on every pull and ships as standard equipment on all Gen6 pistols.
• Flared magwell on the Gen6 frame speeds up magazine insertion during reloads by widening the entry point, an improvement that benefits competition shooters and anyone who trains for defensive speed reloads.
• nDLC finish on both the barrel and slide provides a hardened, corrosion-resistant surface that resists wear and maintains finish integrity through high round counts and regular holster use.

Practical Benefits

• The crossover layout of the Glock G45 Gen6 (U64550203) gives you the complete 17-round grip and magazine capacity of the G17 while clearing holsters faster and handling more like the compact G19, making it a natural fit for competition shooters running Carry Optics divisions.
• The factory optics-ready slide with three included adapter plates means you can mount a red dot to your G45 Gen6 the same day you take ownership, with no gunsmith appointment or aftermarket slide purchase needed.
• Three included 17-round magazines give you immediate range capacity and two ready spares for training, competitive stages, or home defense staging without adding to your first-day cost.
• Removing finger grooves from the Gen6 frame makes this 9mm crossover pistol a better universal fit across family members or team members with different hand sizes who share a single platform.
• The G45 Gen6 accepts all standard G17 and G19 compatible magazines and fits existing G45 and G19 holsters without modification, protecting your current accessory investment as you transition to the Gen6 platform.
• If you are a competitive shooter, duty carrier, or home defense-focused buyer looking for a 9mm platform that gives you full-size capacity in a shorter, optics-ready package, the Glock G45 Gen6 Crossover (U64550203) is a capable tool built to perform from the first round to the last.
