cool first post, just to come bash a company that seems to have made things right for you. great!!!! lots of us hear have the "slim" or pt111/140 series of pistols and are very happy with them, this is actually the first complaint I ave heard regarding the firing system. but I am glad their CS made it good on your end. enjoy your new Glock
full-auto on an sa/da striker though, that is odd to say the least, but it is a slightly complicated trigger design, i'll have to take a better look at mine to understand how that could happen. I would assume it would have something to do with the trigger itself and not the grip/frame, something letting the sear break after the pre-cock of the pin. just odd that they couldn't just replace the trigger system. or maybe more likely, it is such a cheap pistol they would just as rather send a new one than spending time and laboring repairing it.
