When I pulled the slide you can watch the slide release tilt up on the outside of the frame if you pull hard enough you can get the slide to go all the way back and then when the side comes forward it doesn't go all the way forward just likes a little but you can push it forward all of this with an empty magazine . If I could go shoot the gun in a few days I would to test it's just bothering me not knowing if all is good. I guess I've never pulled the slide back with an empty magazine on this gun before.
