I don't know, I have a 92FS made in Italy and the only thing I've found on it made out of plastic are the grips. My son has an M9 purchased fairly recently and the only thing I saw on his after seeing a post about all the plastic parts on Berettas is the guide rod and the grips. Mine has a steel guide rod. As for CZ vs. Beretta? I say Beretta because I have one, love it, wouldn't sell it or trade it off for anything and it's slicker than slime on glass. I don't want to shoot a CZ because I don't need a new addiction! I have handled the Armalite AR24 that is supposed to be a modern copy of the CZ (and it's actually on my short list) and I used to have a Tanarmi/Tanfoglio imported by Interarms that was essentially the same thing best I recall. It was years ago but it was a heck of a good shooter and very reliable. The Beretta is a proven, rock solid pistol that flat out works and Lord willing I will always own at least one. The CZ has a proven track record and it's share of CZ-Fanboyz so I'm sure it wouldn't be a bad choice either....However, Glock has more fanboys than any of the modern pistols and and other than being reliable (which is also true of 99.999% of the pistols made today) I'm not sure what folks like about them! Pick the one that feels best in your hand, points most naturally and that you simply like the most. It would be hard to go wrong.
