Was that slide locking issue widespread? Sometimes people shooting style causes that if your thumb drifs up. I meant to try this when first testing the gun to see how far out of my normal grip my thumb would have to move to cause this. I just looked it over right now and it seem that the molded spot for you thumb slightly prevents accidentally slipping up. If you have you thumb on the slide stop it takes barely any for to push it up high enough to lock the slide.militia_man";p="65450 said:I also read about a problem with the slide stop engaging after every shot and locking the slide open as if the gun had fired the last round. How much did you pay for it? Did you purchase from a gun shop or from a private seller?
