SGM Tactical .40 S&W 31-Round Extended Magazine for Glock 22, 23, 27, 35

This is an SGM Tactical .40 S&W 31-round extended magazine for Glock® 22/23/27/35 pistols.
Featuring glass-reinforced polymer construction with the same reinforced feed lips, steel inserts and witness holes you’ll find in a stock Glock-compatible magazine—SGM Tactical’s magazines can withstand extreme conditions and feed your pistol more reliably than any other aftermarket magazine available today.
SGM Tactical magazines offer a reliable alternative to factory Glock magazines with superior construction, a 5-year warranty and a price that practically anyone can afford. Featuring precision CAD and cutting-edge design, these are some of the best everyday magazines you could buy for your Glock pistol.
Note: High-capacity magazines can come with especially stiff springs. Try loading half the listed capacity and leaving the magazine overnight to ensure easier loading in the future (or use a speedloader).
