Identifying the CZ75 Pre-B

[Te_Master]

Hello,
Wanted to check why this model have that extra pin circled in photo and adjustable rear sight. Cant find any 86' model with that extra hole on and im not sure why is it for. For rear sight, owner said that adjustable rear sights were original on, but also cant find any 86' model with those sights on.
The original hand grips were black plastic, same as 86' models'. Don't have gun with me to check year markings on, but i think its manufactured in 86' from different descriptions and photos from this forum.

Just wanted to get more information for this model from you guys.

No one have clue what those extra hole pins are ? That are red circled in photo? Im curious why are there.

I’ve seen it in some imported competition cz75s, I think it is for holding the sear cage still to improve trigger break/pull.  Not sure if it allows adjustment of the sear as well. 

Pics of the inside of the frame?

Looks like the sear cage is pinned to the frame like a CZC A01...

Sorry dont have inside pics, im actually looking to buy this gun, and only have this two photos.

Does that mean, pins are aftermarket done or they are original with CZ75 ?

I would guess the slide stop, rear and front sights, and probably that frame/sear modification were done after the factory.

 I'd agree that has a number of aftermarket/non factory parts. I also think that hole/pin is for the sear. Based on the mods that are visible it wouldn't surprise me if there are more internal ones. That's not necessarily good or bad if it's well done depending on what you want. But those grips are atrocious.

If it were me, and the right price, would be interested in it as a range toy rather than a collectible - I would guess it has a sweet trigger.

Well this would be my first gun. This is what i would get for around 750€ - Original grips, 9mm mags + reloader, .22 mags and a Kadet .22  adapter.



I just wanted to know, if they are original and why those extra pins are there and if there was original CZ75 adjustable sights on

Securing the sear cage was a top of the line aftermarket improvement. Not sure if that’s what the pin is for, but don’t know what else it could be. Would bet the hammer has been reshaped to take out the creep. Another old improvement before we had excellent competition hammers. With all the stuff pictured and 2 Kadet mags I’d spend $1,000 on it. Looks like a well cared for setup.

Pistol update. Got a chance to try and shoot it and also checked the markings. Awesome gun and a sweet trigger puller with a good sights.

Observations:
- Sights seems to be custom made, adjustable from Peter stahl
- Seems that manufacture year is not visible on the gun. Could be on any other location?
- Close up of additional pin on a back of a gun. (as said before - sear cage improvement ?)

Owner does not know much about pistol, because it was bought like this from previous owner which was brought here from Czechoslovakia at that time.

The year was marked only in that oval, many times it was roughly done. If you look at the top of this pistol forum, there’s a CZ 75 History and serial range section where you might be able to find where the serial number of your pistol places in the year of manufacture. Congrats on an interesting specimen with a great trigger.
