40 cal aint dead, neither are these magsI know everyone and there mother switched to 9mm but some of us still love the 40 and these KCI mags keep my G22 running smooth. 15 rounds, drops free, feeds everything from cheap Remington UMC to Speer Gold Dots. Ive got 6 of these now and rotate them through range days and practice sessions. Probably 1500+ rounds total across all of them and not a single failure to feed. The fact that they fit my 22, my 23, AND my 27 is awesome!! One mag to rule them all basically. At $13 each Im stocking up before they figure out they should charge more.
Cross compatible with G22, G23, G27, G24, and G35
Reliable feeding across a wide variety of ammo typesWould be nice if KCI offered an extended baseplate option
