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. Current pricing and availability for every model we carry are in the product listings below.
How to buy: pick up in person at either store, or order online and we ship to your FFL. Not sure which model fits your hand or which optic plate you need — call the counter and we will walk you through it.
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.
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.
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.
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. The Gen6 optic bed is a different, deeper cut than the Gen5 MOS recess, and it uses its own plate set. That is not a problem in practice, because three plates come in the box covering the RMR, Shield/DeltaPoint/Holosun K and C-More footprints — between them, most dots on the market. Bring your optic in if you are unsure which plate it takes.
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.
