im a new glock owner, ive owned revolvers and long guns up until now and i have a question about my model 36. Should the slide come off when i dry fire it??? I dry fired it to get ready to field strip it and the slide just came on off without me first pulling it back and releasing it. Is this normal. Sorry for the dumb question but as i said i dont know too much about the gun being i just aquired it. Any help will be greatly appreciated.
