Well, me being new to the world of pistols, I have a question for the ones that know more than me. I was told on one of my videos on YouTube that it isn't OK to close the slide with the slide lock (not manually letting it come forward slowly) letting the slide fly forward without a round in the chamber. I was told it should only be slowly brought forward manually when dealing with no round in the chamber. Well, I know the Dry-Firing thing is FUD, but has anyone heard about this and is it true? This is with my P99, so I'd imagine it would be the same for similar polymer pistols. Thoughts?
