Glock 43X versions
The standard 43X has no optic cut and no rail. The MOS version has a slide cut for a slim red dot, mounted with an adapter plate. The Rail version adds an accessory rail for a compact light, and some listings have both. Many of our 43X listings are factory or distributor custom finishes; the pistol under the finish is the same. In stock now: 13 standard, 3 MOS, 2 Rail and 1 MOS with rail.
Glock 43X vs Glock 48 vs Glock 43
The 43X and 48 share the same grip and magazine. The 48 has a longer slide and a 4.17 inch barrel, so it is a little easier to shoot and a little longer to carry. The Glock 43 is smaller and thinner again, with a 6 round magazine that does not fit the 43X.
- 3.41 in barrel
- 10 round factory magazine
- Long grip, short slide
- 4.17 in barrel
- Same magazine as the 43X
- Long grip, long slide
Glock 43X magazines
Glock 43X and Glock 48 magazines are the same. Glock's standard magazine holds 10 rounds, and higher capacity magazines from other makers, such as the Shield Arms S15, fit the same grip; our pistol listings show 10 and 15 round versions. Glock 43 magazines do not fit. We have 20 in-stock magazines that fit the 43X, plus 27 base pads, magwells and extensions.
Holsters, sights and parts
Many holsters list both the 43X and the 48, since they share a frame; the 48 needs a holster long enough for its slide. Sights for the slimline models are their own size, so they are listed for the 42, 43, 43X and 48. In stock and made to fit: 49 holsters, 32 sights, 11 triggers and 23 lights and lasers.
