Both in 9mm. Both similar in price.
Which would you choose and why? I've only handled the CZ and fits me really well.
I do like the accessory rail on the M+P.
i had both, still have the CZ75 (in 40). I sold the MP because I didn't like the 'fit' in my hand, and because of that I sucked at shooting it (even with the 3 different grips). Friends who used my MP had no issues, it was just me.
I love the CZ. To date I have shot 4,690 rounds (yes, i am that annal that i count rounds!) with out a single issue. Eats anything that i feed it.
It all comes down to 'how does it feel".
You mentioned that you like the fit of the CZ, have you handled the M&P? If not, try to find one to handle before purchasing.
Also, the CZ 75 has a model called the SP-01, it has an accessory rail. Two of my range buddies have the CZ75 SP-01 Shadow, its a great gun, shoots very well (maybe a little better than my CZ in 40).
Happy shopping - and what ever you purchase, make sure that you use it an enjoy on a regular bases.
