Glock G45 GEN6 10 Round
About this product
The Glock G45 is a striker-fired 9mm Luger pistol that crosses Glock's compact G19 frame with the longer G17-length slide, giving you a full-size sight radius and slide mass on a frame sized for concealed carry and duty use. It's built with front and rear slide serrations and an ambidextrous slide stop lever, and this listing is the California-compliant configuration with a 10-round magazine in place of the higher-capacity magazine sold in unrestricted states.
What is it used for?
It's a duty and carry pistol that splits the difference between Glock's compact and full-size lines — the G19-sized grip keeps it comfortable to carry and conceal, while the longer G17 slide adds sight radius and slide mass that many shooters find helps with recoil control and follow-up shot speed compared to a same-size compact slide. That combination has made the crossover format popular with both duty carriers and range shooters who want one gun to cover carry and range use.
How does it compare to the standard G19?
The grip and magazine well are the same G19 footprint, so holsters and grip modules sized for the G19 generally carry over, but the slide is longer, matching the G17's dimensions. That gives you more sight radius for aimed shots and a bit more reciprocating mass to help manage recoil, at the cost of a slightly longer package to conceal than a same-frame G19 with its shorter slide.
What fits it?
Aftermarket parts sized for Glock's G19-frame/G17-slide crossover pattern generally fit — holsters, sights, and slide accessories built for this specific crossover combination, rather than G19-specific or G17-specific gear that assumes a matching frame and slide length. Check compatibility with your specific holster or accessory before assuming a straight G19 or G17 part will fit, since a mismatch between frame and slide length is exactly what trips people up when ordering online.
Who is this not for?
If concealment is your top priority, the longer G17-length slide makes this a bit harder to hide under a shirt than a same-frame G19 with its shorter slide — a dedicated compact is usually the better concealed-carry choice. It's also not the pick if you specifically want maximum onboard capacity, since this configuration ships with a 10-round magazine rather than a higher-capacity option. And if you already own a G19 and G17 separately, the G45's main value proposition — one gun instead of two — won't add much you don't already have covered.
Does it work in California?
Yes — this is the California-compliant configuration, with a 10-round magazine to meet the state's capacity limit. As with any handgun purchase here, confirm current roster status with your dealer, and expect the standard DROS paperwork and 10-day waiting period. See California gun laws for the full process, and compare it against the CZ 83 if you're weighing other 9mm-class or DA/SA options while you shop.
Is it worth $1,016.99?
For a Glock crossover pistol built specifically for California delivery with the roster-compliant magazine already sorted, the convenience of buying it ready to transfer is worth something on its own, on top of Glock's reputation for reliability. If you're outside California and don't need the compliant configuration, shop around — you may find the same core pistol for less without the reduced-capacity magazine built in. Factor in the DROS fee and 10-day wait either way, since those apply regardless of which Glock model you settle on.
