Ok...I'm not trying to start a fight here or anything just would like to know of any issues that Glocks might have? I know of the recoil spring in the gen4, but was wondering if there is anything that I should watch out for? Like shooting with a limp wrist or what ammo's don't work. I am going to be purchasing a Glock 17 in 9mm probably by the end of this week if everything works out money wise. Any help would be appreciated.
