What calibers does the G43X come in?
Every current version is chambered in 9x19 mm.
Is the G43X optics-ready?
Of the 11 versions, 6 have a Slimline MOS slide cut for micro dots; 2 have a Slimline MOS slide cut for micro dots, with a factory Aimpoint COA installed; one is cut for Aimpoint's A-CUT interface, with a factory Aimpoint COA installed; and 2 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 G43X 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.
What's the latest on the G43X?
Nothing new on the G43X lately.
