enjoy the necro, but I don't think valve would add a p2k cyrex. just like how they didn't add the asiimov for the m4a1-s because the m4a4 already had the asiimov, and they're not adding the cyrex for the m4a4 because the m4a1-s already has the cyrex design, they're not going to add it for the p2k because the usp-s already has the cyrex.
