I've always used 115 or 124 grain with my Nines, but yesterday ordered a bunch of 147 to experiment with. I did a little searching to see how other people liked 147 in the respective guns I shoot: Sig P226, Walther PPQ, and CZ75B. The Sig and the Walther appear to happily gobble the heavier bullets, but I did see some sporadic commentary about the CZ75B apparently having a shorter OCL and therefore having some trouble with 147 grain. I'll test my own in a week or so, but I'm just curious how much of an issue (or hopefully non-issue) this is. How well does 147 grain ammo function in your CZ75B?
