The Pre B CZ 85 also has an ambidextrous slide release set up (levers/releases on both sides of the frame).
There are CZ 75s with ambidextrous safeties. I just picked up a CZ 75SA (single action only) that has the ambidextrous safeties very similar to the CZ 85's. It does not have the ambidextrous slide release. However, if I ever have it refinished I think I'll have the right side hole enlarged and install a right side slide release. Say right side slide release 3 times real fast.
Some (maybe all??) of the stainless CZ 75's made these days have ambidextrous safeties and with the right grips those are some pretty handguns, too.
The SA does have the firing pin block safety though.
And there is the Omega CZ 75 and the Urban Gray CZ 75, both of those have ambidextrous safeties as well.
I can't say my experience with a Pre B CZ is typical but I've put a lot of money in my Pre B CZ 85 so far.
Just to make me fell better I put new springs and new pins in mine and that cost about $70.
I found the barrel/chamber were pitted pretty bad so that was a new barrel. Anywhere from $150 to $190 with shipping.
Will it be worth it? That's up to the guy spending the money. If I'd paid someone else to install the new parts and fit the barrel to the frame and slide I'd have spent a lot more money. In the end, when I'm done with it, between parts and refinishing, I'll have over $800 in mine. I could have had a new one and bought some custom hammer/trigger parts for that money.
Just think about what if might cost you. If you can look it over before you buy it you may find it's condition either makes it worth it, or not.
Good luck with it though, either way.
