What calibers does the G45 come in?

Every current version is chambered in 9x19 mm.

Is the G45 optics-ready?

Of the 7 versions, 2 are cut for Aimpoint's A-CUT interface, with a factory Aimpoint COA installed; 2 are Gen6 models with GLOCK's optic-ready slide; and 3 aren't set up for an optic. Some of these optics details come from a retailer listing rather than from the maker.

How much does a Glock G45 cost?

Glock doesn't publish suggested retail prices, so the best guide is what stores are charging. Tap “See prices” next to any version to see what retailers are asking.

Can you buy one in California or Massachusetts?

California and Massachusetts each keep their own list of handguns approved for sale, and a gun has to be on it before a dealer there can sell it to you. State rules change, so check our California and Massachusetts pages before you buy.
