Now I have to admit I am a bit of a Sig fan boy.."however, I will tell you that when I picked up my CZ 97B, I could tell it was a match made in heaven. I have fairly large hands...well, long fingers and the gun fits beautifully. The ergonomics are superb. If it shoots half as well as it fits, I am a very happy camper. it is a big gun and a heavy gun but for 45 acp, that is exactly what I want.
In hindsight, I would probably prefer the 97BD, the night sights and the decocker (sig fan talking here) are probably worth the diff in MSRP but I got impatient.
