CZ-75 and CZ-75B

The older one doesn't have a firing pin block. Supposedly this means that if you drop it and it lands barrel down such that the inertia of the stop makes the firing pin jump forward it "COULD" set off the round in the chamber. With the "b" model the block prevents this happening since the firing pin block has to be retracted by the movement of the trigger before the hammer can knock the pin forward.
What it does in terms of the shooter is makes the trigger of the guns with the block a touch harder to pull since there's one additional step involved. This is why the competition oriented Shadow does not have a FPB.
The only other thing is that the finish or coating on the older "plain" 75's is not as thick or durable as the new polymer coating used on the new guns. In fact it reminds me more of a basic Parkerized finish. My 20'ish year old pre-b has a few slight bare lines on the ridges of the slide and frame as a result of holsters and handling as a result.
Frankly, for the way we use our handguns here in Canada at the range only the older pre-b 75 is a very good gun if it passes the usual inspections. All else being equal it should have a better feeling trigger than the "b" models due to the one less function during the trigger pull.

In my experience "no". I'm using my modern Shadow mags in my pre-b and the old all metal pinned mag from the 75 in my Shadow without issue. But to be fair my pre-b is one of the last ones made in the early to mid 90's. Mags from earlier 75's may have been slightly different.
I did need to very lightly squish a couple of the newer magazines inward to allow them to drop free in the old 75. They fit but with just enough drag on a couple of high points that they needed just a slight tweak. The change didn't affect how they work in my Shadow.

Not even squishing (and I did try that) helped in my case. Simply would not seat. The difference is very subtle and it was imposible to determine what dimention was out of wack.
Worked fine in a newer CZ75B but not in my 88 pre-B.
Could have been the difference between a no-name mag and an actual CZ mag. Ended up purchasing CZ 75 specific mags from CZ Custom Shop.
Try before you buy.

Montey, was it a case of the mags not inserting far enough to catch on the magazine lock? If that is the issue it's possible that a previous owner already opened up or otherwise modified the base of the frame to allow mine to fit. Certainly in my case I've done nothing to my gun yet it accepts the plastic end 10 rounders. Genuine CZ mags though. And they only just barely fit deeply enough to catch the lock. Nary the space to fit in a thin hair is left.
All that I can say is that I purchased 3 no-name mags that would not seat in my pre-b 75. A young person put a need help notice on GN for extra mags to complete his BB course. I lent him my set of 5 mags (2 original and 3 no-name) and he had no issues with any of them in his 75B. Ended up giving him the no-name mags as they were of no use to me. Ordered 3, CZ75 mags from CZ Custom and have had no issues. The no-name ones would not seat and locked up approx 1/4" from seating home.

The front corners of the older magazines more round whilst the later magazines had squared off corners. The magazine well of the 75 was rounded to accept the magazine but the newer magazines (square front) would foul at the upper end of the well. What I did was field strip the pistol, mark the contact point and open the corners of the well with a small diameter round file. Working carefully and chaecking often were the watch words. It only took a short time to get the mags to fit. As I recollect the length area needing work was 8 - 10 mm.

I picked up this CZ-75 a while back.
I dont own a CZ-75b but maybe this pic might help out ?
The original mag was preventing the action to stay open after the last round. I picked up a brand new CZ mag (intended for 75b, Shadow etc) at Target Sports and it now works perfect on this older CZ-75.)
It required no bending or fiddling -- Mind you the mag rattles when it has 10 rounds in it, hence Ive only purchased one --- still looking for one that wont rattle when its loaded.
...
CZ changed the inside dimensions of the mag well when they brought out the 75B. My old CZ85 Combat made in 1988 had the smaller dimensions. Newer mags would not seat in the gun. In fact they would only go in about 3/4 of the way. A dremel solved the problem. If you get a Pre-B that works it likely is either a transitional model or someone opened up the magwell area as I did.
I sold the gun because it had the round dovetail cut for the rear sight and I just found the sights on it to hard to pick up quickly. Whoever bought the gun from Gunnar got a good one. The trigger was as smooth as glass and the gun was as tight as the day it left the factory after god knows how many rounds through it.

I have a pre-B CZ 75 and absolutely love it. But here's the question. Rentention holsters?
I know BladeTech makes a passive rentention holster, and there's Fobus and iTac out there, but what I'd really like is a SafariLand 6285 holster.
My question is does anyone have expierience with the holster and a pre-B model? And second where do you find them? I've found them on optics planet, but not sure of the customs charges involved...
Thanks!

If the holsters are made in the US you might get charged with HST/GST plus an handling charge of $5. from the Post Office. I say might because most of what I have bought from the US comes up without being charged HST/GST. Seems like it hit or miss with Customs.
No experience with the holsters you mentioned.
