Glock 43X

The Glock 43X bridges the gap between the single-stack G43 and the double-stack G19. It uses the slim slide from the G43 but pairs it with an extended grip that holds 10+1 rounds in a single-stack configuration. The result is a highly concealable pistol that offers better capacity and shootability than the original G43.

The 43X has become extremely popular due to Shield Arms' S15 magazine, which replaces the factory 10-round single-stack mag with a 15-round double-stack design. This aftermarket magazine transforms the 43X into a slim pistol with G19-equivalent capacity, creating what many consider the ultimate concealed carry combination.

The slim 1.02-inch width makes the 43X exceptionally comfortable for appendix carry, while the extended grip (same length as G19) provides full purchase for all fingers. The Gen5 Silver nPVD slide finish matches the factory two-tone appearance. For shooters prioritizing concealment without sacrificing capacity, the 43X with Shield Arms magazines is hard to beat.
