So i just purchased some Glock factory magazine extensions (not pearce) for my G26 and installed them last night on two of my 10 round magazines. I like the way they feel and The extra two rounds is a bonus. The QUESTION i have for any of you Guys/Girls is does this affect the reliability of the magazine to feed ammo since the spring now has a little more distance to travel? Has anyone ever had any problems with this extension? Wanna kill these ads? We can help!
