My perfect carry gun is actually a perfect series of several guns. The base model is the DAO S&W 3953 but if conditions allow I'll upgrade to the 6946 or 5943. I keep a CS9D around in case the 3953 proves to be too large, but in reality I'd be perfectly happy with just the 3953 and 5943,.......and a 5946 for home duty. A bunch of different model numbers but really just a single gun(with slightly differing weights and capacities).
