I’m a die-hard fanboy when it comes to Glocks and glad you got one in your hands today...a 10mm no less!
I own four Glocks and all have been utterly reliable. Otherwise I wouldn't have kept buying them. Same with my S&W's. I find it very odd that someone would claim to have owned four and five Glocks, but then declare them unreliable junk. Why in the world would you keep buying them if they didn't work?
