I own both the Beretta, an older pre-b 75 and have a CZ SP-01 Shadow.
I found my head nodding in full agreement on all counts with psyopspec's post. His experience mimics my own on all counts.
Up this way handguns are sporting tools. But I use mine in IPSC and IDPA matches a lot. So perhaps there's a bit of "performance under pressure" that you may relate to your own experience and needs.
My pre-b model 75 is my go to gun for IDPA. I've used my Beretta for our IDPA practice nights but I seem to switch the decocker/safety inadvertently a few times too often to trust myself to use it in any matches. So it's pretty much become a range toy. But I do like the gun enough that I'm going to keep it.... for now at least.
I take large to Xlarge gloves depending on brand and style. So while I don't have the largest hands they are bigger than average. Even so the Beretta is a handful. I don't have any accuracy issues with the first double action shot coming out of the holster but it's likey not too far from that point. Coming from a CZ75 you would most certainly notice the little extra reach needed for that first shot situation. I know that I do if I shoot them back to back at all. But once into SA mode after that first shot each is about a wash in relation to trigger pull. Espcially if you train to ride the reset point instead of fully releasing the trigger for each shot.
Sitting on the table the Beretta is a slightly bigger gun. But the alloy frame makes it a slight bit less noticable when riding on your belt. Nothing like the difference from the CZ to a polymer gun. Just enough to notice when you stop and consider it.
Oh wait... I'm thinking about the Shadow to Beretta. The plain jane 75 is within two ounces of the same weight at the Beretta. So I'd call it a wash. No one can tell that slight a difference in pull on the belt... .
92fs vs m9? I doubt there's enough to notice. Mostly it's the straight vs slightly angled lower line to the forward dust cover. I can't imagine that they would feel any different to actually handle and shoot.
All in all I find that the CZ 75 platform just becomes part of me. It sits in my hand like it was designed to fit me from birth. To draw and shoot my CZ it feels like my hands just suddenly sprouted sights and the ability to go "BANG!". On the other hand the Beretta never blends with you like the CZ does. You always know you're holding something out there. It shoots just fine. Darned nice in fact. But it simply never seems to dissapear in my hands like the CZ's do. Possibly because I'm always thinking about the upcoming reload and concentrating on not pulling the decocker/safety down when I rack the slide.
Now if I had to carry a gun around all day on my hip in the real world instead of at the range this would have a whole other ending. Both the CZ and Beretta are big and heavy for a CCW gun. If I were allowed to carry CCW I'd be all over the smaller and more compact guns in polymer.
In fact in thinking about it the Beretta is the only handgun I have with a slide mounted safety of any sort. It'll likely be the last as well. I won't ditch the gun due to this. I like it too much in other ways to do that. But I likely won't use it in any matches other than our local Speed Steel meets due to the slide mounted control which I just can't get used to avoiding.
