Browning Hi-Power
Love my Sig's, too -- made for combat and a bit loose in all the right places, but if I am not out in the mud and sand, and if I want to put the bullet in the 10-ring consistently, my Belgium BHP is the 9mm of choice. It's tight as a tick, has adjustable sights, and a better trigger. It is incredibly accurate. The only drawback is that it won't go double action on the first round. Half-cocked and locked, with 15+1 ready to go is not a bad option, though, IMHO.
