The SIG P220 is no pocket gun and fits my hand fine. It has an 8 round mag and the P221 would only be a 10 rounder unless you are an LEO. With a grip that size it would be difficult to conceal. Since the major commercial handgun market in the world is in the U.S., and we have a 10 round limit and are going to concealed carry, I do not see SIG making it. I would not have a gun that big to get an extra two rounds in the mag. I like the H&K P7 M8 over the M13 for the same reason. It fits my hand MUCH better. I just don't see much of a market for it.
