I just got a new P99 QA and noticed the slide and the barrel have quite a bit of sideways play in them (very firm up and down). If I hold the gun firmly, I can move it around easily with my other hand so much that I would probably be a foot off @ <5 yards. Also, when I pick it up and shake it, the slide rattles a lot. Is this normal? There is no wear on the inside of the slide rails.
