I'm still new to my P99 AS as I've only had it for a few months now. While cleaning my gun tonight, I noticed that there seems to be some play in the trigger. With the gun not cocked (shooting in DA mode) I can pull the trigger back about 0.5 cm (which doesn't sound like a lot on paper, but it's quite noticeable movement when you actually see it) before the trigger actually seems to engage. I've never noticed this before, but I guess I also haven't really payed attention to it. Is this something normal, or did I mess something up/ not put the gun back together? Thanks.
