That's a difficult question to answer. I do find the CZ more accurate BUT---I've had it for over 10 years- the S&W just a few weeks; The CZ is a double stack with a wider grip which fits my hand better than the S&W; The trigger pull on the CZ has been "smoothed out" from a LOT of shooting since I've had it; the CZ is a little heavier which gives me more accuracy since it's more stable. The CZ is now my target pistol, and the 3913 will become my CCW pistol. The S&W is very accurate out to 20 yards and is much more concealable than the CZ, which is why I bought it. One big advantage of the S&W over the CZ is the ease of disassembly for cleaning and repair (spring replacement, etc.). The S&W can be completely disassembled with very few tools. In order to disassemble the CZ, roll pins have to be removed, etc., so I've never attempted a disassembly. They are both EXCELLENT quality firearms which I will never sell. Each has it's own advantages and disadvantages.
