I am a CZ fan, and I love 9mm and .45 ACP as a semi-auto round. So the 97B was an easy sell. I already have three CZs in 9mm.
Overall I love the 97B. It's a smooth shooting .45 and it does what it's supposed to do. I've put 200 rounds though it between yesterday and today and I only had two malfunctions: one stove pipe, and one failure to feed. So far that's a 1% malfunction rate. I can live with that! My shot placement was consistent (ranged between 5 yards and 15yards). My shots on a whole were hitting a little low, but I have a sneaky suspicion that is a user related error, and not hardware. The double action trigger is nice and smooth, and not a heavy pull as I expected it to be. ...It feels very similar my 75B with a 13 lb main spring. The single action trigger is smooth and easy, and the reset is clean and tight.
My only issue is that the recoil backs the grip screws out so that after about 50 rounds the aluminum grips are loose. That happened last night and tonight. I've ordered rubber grips for it as the aluminum grips make the overall grip surface feel too thin. I have the CZ rubber grips on my 75B and my 75D PCR and I love the feel of them, so I'm hoping they will help fill out some of the width. I'm also considering using blue LockTite to secure the grip screws - unless someone has another solution.
On a whole I am very happy with my 97B - it's the nicest .45 I own.
