Hello. I don't own a CZ97. I have shot a few and the DA/SA triggers were similar to those on the 9mm versions I've shot. All of the ones I've shot were surprisingly good groupers, but some would only feed ball while others gobbled up JHP's with no problems.
The DA trigger reach is pretty far and I'd carry cocked-and-locked were I toting one of these pistols.
My CZ-97 was found used. Got an incredible deal and the gun looked unfired. Production date was '98. First trip to the range showed the weapon was accurate and reliable with all jacketed ammo, including hollow points. While there's not a large number of rounds through the gun I can give some first impressions. The fit and finish (high luster blue) is impecable. NO forward serrations(thank god). The grip fits my hand well, but it is a LONG reach to the trigger for DA use. As Stephen said, I'd carry it DA. Sure, it's not my Colt Government Model, but it cost half the price and is probably 80% as good.
