When I load a mag into my pm9 and then pull the slide back to chamber a round the slide release is so hard I have to use both thumbs to make it engage. I was trying to mess with it to try to figure out what the problem is (with snap cap rounds to be on the safe side). I found that if I push up on the bottom of the mag the slide shoots forward even with my thumb off the slide release. Does this make sense to anyone. Im starting to think that a trip back to it's motherland might be in order. PS. the gun has 250 trouble free rounds through her so far.
