So I know the full size p99 magazines fit in the compact and seem okay so far, but would you trust that setup to carry the p99c and a 15 round magazine with it as your reload? Have you ever found that setup to shift/bind/not feed something that would keep you from thinking its 100% reliable?

The gun doesn't care how long the magazines are. As long as they are machined the same way up top (magazine release catch, feed lips, etc) which they are, you will have no problems. This is the very reason they make subcompacts that take the same magazines. That way, if your primary gun is unavailable, then you can use its magazines with your subcompact, no issues.
