This is a Glock Factory OEM, drop-free magazine for your G22, G23 or G27 pistol in .40 S&W. It is limited by Glock to only accept 10 rounds so it is compliant in states with a 10rd capacity limit. This features a hardened steel insert and is encased in high tech polymer. The polymer coating protects the magazines and prevents deformation, even when dropped from a great height. Compatible with current and previous generations of Glock pistols as well as the Polymer80 PF940 V2 80% gun frame.
Designed for use in the Glock 22 pistols but will also function in the Glock 23 and Glock 27 handguns, there will just be a gap between the end of the frame and the end of the magazine. An X Grip can cover that gap up and give you more surface to grip from. The crack proof polymer construction, full-length steel inserts, numbered witness holes and tough steel springs make the Factory Glock Magazines the best choice when reliability and consistency count. Trusted by military and law enforcement alike.
Glock magazines are known for having very stiff springs when new and may be extremely difficult to load to full capacity. We recommend using a magazine speed loader to assist the first couple of times. Once broken in a little bit the magazine should accept the full capacity of rounds with more ease.
