I shot my glock for the first time today and I LOVE IT.... i have had springfields and 1911-a1's and i love it..... i love how it feels and how it shoots..... I'm sending it in to glock for the lower reciever to be replaced with a gen 3 lower..... how can i get the 3 10rd mags to not be so stiff as in when i put the rounds in it its hard as hell?
