Description
The Glock 45 Gen6 9mm Pistol is the sixth generation update to Glock’s crossover concept: a full-size grip frame mated to a compact-length slide. That combination gives you the 17-round magazine capacity and control surface of a duty gun with a shorter muzzle that clears a holster faster and carries flatter against the body. Chambered in 9mm Luger with a 4.02-inch Glock Marksman barrel and a black nDLC finished slide, it lands squarely between the G17 and the G19 in handling.

What Changed on the Glock 45 Gen6 9mm Pistol
On the Glock 45 Gen6 9mm Pistol the revision is less about a new silhouette and more about refining details shooters have been asking about for years. The frame now carries a coarser RTF6 style texture with a defined palm swell and an integral thumb rest, so the hand indexes the same way on every draw. The beavertail is enlarged, which keeps the web of a high grip from getting pinched by the slide. A flat-faced trigger comes standard, giving the finger a consistent reference surface and a cleaner straight-back press than the older curved shoe.
Optic Ready From the Factory
Every Glock 45 Gen6 9mm Pistol slide is cut for a red dot and ships with a plate system, so mounting a micro optic no longer means sending the slide out for milling. The slide also wears front serrations, which makes press checks and administrative handling easier with gloves or wet hands. Suppressor-height concerns aside, the factory white dot front and white outline rear sights remain usable as a backup if the dot ever goes dark.
Safe Action Trigger System
The Glock 45 Gen6 9mm Pistol keeps the Safe Action arrangement of three passive mechanical safeties that release in sequence as the trigger travels rearward and reset automatically when pressure comes off. There is no manual lever to remember under stress, which is a large part of why this platform dominates duty holsters. Average trigger pull runs around 5.5 pounds, striker fired, with the short tactile reset the design is known for.
Frame, Grip and Fit
Interchangeable backstraps on the Glock 45 Gen6 9mm Pistol let you tune circumference and reach to the trigger, which matters more on a 9mm double stack than most shooters admit. The polymer frame keeps loaded weight down to roughly 21.7 ounces empty, and an accessory rail on the dust cover accepts standard weapon lights. Three magazines are included, which is unusual generosity and removes an immediate accessory purchase.
Barrel and Accuracy
The Glock Marksman barrel uses enhanced polygonal rifling with a 1 in 9.84 inch twist, and in practical terms it tightens group size noticeably over older Glock barrels without changing maintenance habits. Overall length is 7.44 inches, short enough to conceal under a jacket yet long enough to give a useful sight radius.

Who Should Buy It
The Glock 45 Gen6 9mm Pistol is a strong choice for duty carry, home defense and shooters who want one handgun that works for both range training and concealed carry. Full-size grip real estate helps recoil control and reloads, while the shorter slide keeps it manageable under cover garments. Be aware of the trade-offs. The tall grip frame is the hardest part of any crossover Glock to conceal, so appendix carry with a tucked shirt takes planning. The aggressive Gen6 texture is fantastic for retention and can be abrasive against bare skin. Holster and light selection is excellent but Gen6-specific accessories are still catching up, and shooters who prefer a curved trigger or a manual thumb safety will not find either here.
For most buyers those are small prices to pay for a proven, low-maintenance handgun. Browse comparable handguns in our firearms collection, or review the manufacturer specifications at Glock.
