The Glock 43 is a subcompact 9mm pistol introduced to the US civilian market in 2015, to much fanfare. It was a follow-up to the Glock 42, an earlier handgun of similar dimensions, but chambered in .380 ACP. Although many liked the G42, many more loved the G43 because 9mm is a more common and plentiful chambering.

However, one of the most significant drawbacks of the Glock 43 is the low 6-round magazine capacity. If you carry a Glock 43 and want to know the best Glock 43 magazine extensions available today, you’re in the right place.
