Glock’s sixth generation arrived in January 2026 and changed four things that matter: a reshaped grip with far broader RTF6 texture, a flat-faced trigger, a new optic mounting system that seats the dot deeper in the slide, and a reworked slide and internals. It comes in three models — the full-size G17, the compact G19, and the G45 that pairs a G19 slide with a G17 frame — all in 9mm. COA versions add a factory-mounted Aimpoint enclosed red dot. Everything in stock is listed below, including New Jersey 10-round configurations.
Buying in New Jersey: we stock the G17 Gen6 and G45 Gen6 in 10-round configurations, identical to the standard-capacity guns apart from the magazines. The G19 Gen6 is currently available to us in 15-round only — ask and we will tell you when the 10-round version is expected. You need a Permit to Purchase for each handgun, and our counter staff walk customers through it every week. Out-of-state buyers can order standard capacity and we ship to the FFL of your choice.
Gen6 looks like a Glock on purpose. The differences are in the hand, not the silhouette.
Full size
The 4.49-inch full-size duty pistol, and the model most Gen6 changes were designed around. Longest sight radius of the three, the easiest to shoot well, and the one to pick if it is living in a nightstand or a duty holster rather than under a shirt.

17-round version ›
Compact
The 4.02-inch compact, and the most carried handgun size in America. Short enough to conceal on a belt, big enough to shoot like a full-size. If you are buying one Glock to do everything, this is still the answer.

15-round version ›
Crossover
A G19-length slide on a G17-length frame. You get the full grip — every finger on the gun, more control, more rounds — with a shorter slide that clears a holster faster. A lot of people who think they want a G19 actually want this.

Factory optic
An Aimpoint COA enclosed 3.5 MOA red dot mounted at the factory on an A-CUT slide, with metal co-witness backup sights. The optic seats into a dovetail machined in the steel rather than riding the polymer plates, which is the more robust of the two mounting systems.
Currently stocked in standard capacity only
G17 COA ›Every standard Gen6 ships optics-ready with three adapter plates covering the RMR, Shield/DeltaPoint/Holosun K, and C-More footprints. The plate is polymer and sits in a recess, acting as a crush washer while the optic screws directly into the slide. It works, it fits almost any dot you already own, and the deeper optic bed puts the dot lower than a Gen5 MOS ever did.
The COA models skip plates entirely. Aimpoint’s A-CUT machines a full-length dovetail into the slide and locks the optic in with a front hook and rear wedge, so recoil transfers into the dovetail wall instead of the mounting screws. The optic is enclosed and nitrogen-purged, so it does not fog or fill with lint the way an open-emitter dot can. You are buying a specific optic rather than a mount — the trade is flexibility for durability.
If you already own a red dot, buy the standard Gen6. If you want a duty-grade optic installed and zeroed with nothing to think about, buy the COA.

Yes. Magazines carry over, and so do backstraps and sights. What does not carry over is most of the rest — the slide, barrel and the majority of internals are Gen6 specific. A handful of small parts interchange, but treat Gen6 as its own parts ecosystem when you are buying anything beyond magazines.
Usually. External dimensions barely moved between generations, so most kydex and leather designed for a Gen5 will take a Gen6 of the same model. Fit can be tighter on minimalist holsters, and anything with an optic changes the picture entirely. Bring your holster in and we will check it against the gun.
The slide is the same length on both. The G45 has a full-length G17 frame, so you get a longer grip — all four fingers on the gun for most hands, and 17 rounds instead of 15. That makes it easier to control and slightly harder to conceal at the belt line. If you carry outside the waistband or you have larger hands, the G45 is often the better gun.
No. New Jersey’s magazine limit is 10 rounds and it remains in force — a federal appeals court struck it down in July 2026 and stayed its own ruling in August. The pistols themselves are sold here in 10-round configurations, which is what we stock for New Jersey buyers.
It depends what you mean by better. The flat face gives more consistent finger placement and brings the trigger slightly closer, which helps shorter-fingered shooters. Opinions on the pull itself split: some testers find it essentially unchanged from Gen5, others find it breaks a little cleaner. Dry fire both before you decide.
For most owners, no. The changes are refinements rather than a performance shift, and a Gen5 that fits you well is still an excellent pistol. The strongest case for upgrading is if you shoot a red dot and want the lower optic mounting, or if the Gen5 grip never quite suited your hand. We cover this in detail in our Glock Gen 5 vs Gen 6 comparison.
