You said "Duty/Carry Weapon"- have you checked with your potential agency to see which one's are (or not) on their approved list?
Me? I have CZ's and had a FNP9 (haven't managed to bring home a M&P yet). If the decision were mine, I honestly think I would carry a CZ75BD over my issued Sig P229. And for the sake of your question- I would go with the CZ (if allowed).

I'm going to use the words "clip" and "Long Colt" every chance I get. It grinds my gears to see new members attacked when we all know dang good and well what's being refered to.
