After reading and reading here in the forums, I found out that I could dry fire my glock in order to get used to it and the trigger, so after 10 minutes decided to check the manual and started to strip it, thats when I accidentally press the trigger and then got a bit nervous cause you are not supposed to do that and put the slide back again with just enough force to lock it in place, but it did not go all the way in and is stuck in that position.
I will try anything you guys can suggest to tru to take the slide out and fix my brand new gun which I haven't even fired. Man, I shouldn't have played with it.
