About this product
The Glock G45 Gen6 9mm Pistol is a compact-slide, full-frame duty weapon with MOS optic mounting and 10-round capacity.
What is the Glock G45 Gen6 used for?
The Glock G45 Gen6 serves as a duty, defense, and competition firearm with balanced handling characteristics. Its 4.02-inch barrel provides 1150 fps muzzle velocity with standard 9mm ammunition, while the MOS system accepts micro red dots like the Trijicon RMR for rapid target acquisition. The 10-round magazine capacity complies with restrictive jurisdictions without sacrificing grip ergonomics.
How does the Glock G45 Gen6 compare to the SIG Sauer P320 Compact?
The Glock G45 Gen6 offers superior aftermarket trigger compatibility compared to the SIG Sauer P320 Compact. While the P320 features a modular fire control unit, the Glock's 24.5-ounce weight and 7.5-inch overall length provide better holster compatibility across retention systems. The MOS mounting system requires no adapter plates for most optics, unlike the SIG's proprietary cut.
What does it weigh and what are the dimensions?
The pistol weighs 24.5 ounces unloaded with dimensions of 7.5 inches long, 5.47 inches high, and 1.34 inches wide. The compact slide measures 6.85 inches in length while maintaining full-size frame grip circumference of 5.47 inches. These specifications create a 0.87:1 slide-to-frame ratio that reduces muzzle flip by approximately 15% compared to standard compact models.
Who is this NOT for?
This pistol is not suitable for users requiring maximum concealability or jurisdictions permitting standard capacity magazines. The full-size frame adds 0.6 inches to grip height compared to subcompact alternatives, increasing print through clothing. Those in unrestricted states should consider our Freedom Finger™ M&P® 2.0 Forced Reset Trigger for higher capacity platforms.
What's in the box?
The package includes one Glock G45 Gen6 pistol, one 10-round magazine, MOS mounting hardware, cable lock, and cleaning rod. Magazine capacity is permanently limited via internal block rather than pinned baseplate, maintaining standard external dimensions. All MOS screws are torqued to 15 inch-pounds at factory with Loctite 243 applied.
Is the Glock G45 Gen6 worth it at $557.99?
At $557.99, this pistol delivers competitive value for MOS-ready platforms in restricted states. The investment covers nitride-finished nDLC slide treatment and front serrations that typically add $120-$150 to base models. For technical details on compatibility, consult our FRT Binary Trigger ATF Regulatory Status guide before purchase.
