I have no idea what the reputation of the Witness or the CZ is, although they are certainly good guns in 9mm. The S&W 10mm pistols, however, are impressive. My personal experience is limited, but I have used a 1026 which my son gave me many years ago. Despite the fact that my hands are not particularly large, the 1026 does fit my hand well, and has reasonable recoil with full power ammo. It shoots to POA, and has been completely reliable. From what I've read, the S&W pistols are plenty strong enough. I wouldn't tell you not to investigate the other guns, but if an S&W fits your hand, I don't think you'd be sorry with the choice.
