I tried the P7 in production, but the reloads killed me. My Glock and Steyr are a lot easier to reload.
The short sight radius is another weak point of the P7.
9x19 in M10 mags works fine and they are a lot cheaper to boot.
So far it looks like there is no one majik gun for Production. Para, Glock and Sig are ruling the roost right now.
