## What Customers Say

*AI-generated insights from customer reviews*

The G45 MOS has a strong following among Glock owners who prefer the full-size frame. Owners appreciate the Gen5 improvements, particularly the nDLC finish, which holds up well to regular use. The MOS8 optic cut is noted for its precision fit, and the Aimpoint COA bundle makes the ready-to-shoot optics setup a common draw.

The Marksman barrel gets consistent positive feedback for accuracy. The flared magazine well is appreciated by competitive shooters for faster reloads, though some casual users consider it unnecessary. The ambi slide stop is considered a practical addition for left-handed shooters.

The G45 MOS package with the Aimpoint COA sits at a premium price, and opinions vary on whether the bundled optic justifies the cost versus buying components separately. Three 17-round magazines in the package are well-received. A long-standing mild criticism of the Gen5 platform is the trigger reset, which some shooters prefer to replace with aftermarket options.
