Made from high strength Polymer, these magazines are designed to fit the Glock G44 in .22 LR. These magazines are made to mimic the size and shape of the Glock G19 magazines. The magazines feature an integrated load-assist button to enable quick and easy loading of all 10 rounds, and the rail allows for easy viewing of the remaining rounds in the magazine.
You need to make sure the last round loaded is pointed with the rim all the way back and the bullet pointed up slightly or you might have failures to feed. All in all a very good product. Mini Mags see to work the best, round nose bullets.
Typical Glock quality. Fed great. Well made as always. Assist helps you load bullets.
