Wow, that's a lot of backstory in just a few minutes. As always I learn so much new from your videos and I really appreciate that you are doing this. In a recent CZ marketing video I think they showed a bit of the more modern version of the steel frame casting you showed briefly, I wasn't aware that you could do that sort of casting effectively for steel. I wondered if they were only doing that for aluminum framed pistols, but I guess they've been doing it in steel quite successfully for decades. Thanks again!
Thanks mate, yeah it was necessary to streamline the production. They used the same technology for later versions of CZ70s as well. Quite an interesting technology... :)
I bought my 1st generation CZ75 in 1979, made in 1978, serial № 14xxx. Fine blue finish, but there were a few problems. The forward end of the frame was prone to cracking with heavy use and some had oversize groove diameters. Mine slugs at .358". According the author J.M. Ramos - "The CZ75 Family - The Ultimate Combat Handgun", the frame rails were extended by about 2cm after approximately serial № 27 000. A hammer safely notch was added after serial № 20 000. South African gunsmiths Bruce Wentzel and Phil Spencer patented a recoil buffer which replaced the recoil spring guide rod. I fitted one of these and have had no evidence of cracks after thousands of rounds over more than 30 years. J.M. Ramos states that the first 1 000 or so pistols were made in Spain (as stated) and had an exceptional finish. They were sent to European dealers as promotional pieces and some went to Canada. They are now highly regarded collector items.
Good stuff, here! Not sure who first used investment casting as a shortcut to forming complex shapes but I know that this was Sturm Ruger's main thing and they got their start quite a bit earlier. Ruger also did bluing from the beginning and few of their guns exhibit pits or other surface defects. IMO, if you have defects visible after machining, either your mold was damaged/inferior or you were trying to get too close to the final dimension in your initial casting. (Maybe both.)
Yeah the second idea came to my mind as well - they were trying to get too close... That saves time and money for sure :) also not sure who did it first but bless him for this idea, really clever :)
good video series, but you should mention the differences between the cz75 and cz75b frames. That would be nice. for example the way how the safety lever is spring loaded and the shape of the trigger part... because i am searching for a cz75b pistol and noticed that kind of stuff while i am searching for those pistols. ouh, and the shape of the hammer.. with round hole and the flat one
Hi Kuba: I have really enjoyed your informative videos! I just purchased my first CZ, a model 75B High Polish. Can you please tell me in which years this model was produced and approximately how many were manufactured? Thank you. Kind regards
Hey, hard to say indeed. CZ always made various batches for different markets. I checked my resources but found no particular information. There could have been some high polish guns made for a specific market in some specific year, another batch for another market couple of years later.... really hard to say
This clears up a lot of misconceptions I had about the early CZ 75, thank you! So to summarise: - 1st model (short slide, "waffle" grips, no half-cock notch, 8 mm hammer) has a forged frame made in Czechoslovakia; - early 2nd model (long slide "waffle" grips, half-cock notch, 5,9 mm hammer, "Made in Czechoslovakia" stamped in one line with a 1,8 mm font) has a cast and milled frame made in Spain; - late 2nd model (as above, but with "Made in Czechoslovakia" stamped in two lines with a 2,5 mm font) has a cast and milled frame made in Czechoslovakia. Did I get this right? I've always thought it was the 1st models that had Spanish-made frames. Is there any truth to the claim that the 1st model frames were prone to cracking or was the switch done just to streamline mass production? By the way, the name of that Spanish company translates to "Alfa Sowing Machines", apparently they're still around. I wonder if they're one of those small Eibar companies who used to make Ruby pistols and copies of American revolvers but later switched to making domestic appliances.
You have it right! That is how it was. As for the longer rails it was certainly for durability. The older short rail versions were prone to crack sometimes. Partially it was because of the quality of the spanish steel but I am sure there were other problems as well. Once the Czechoslovaks managed to implement the technology here, all issues were gone :) always better to make the stuff in-house I guess
@@CzechoslovakGunStories Thanks Kuba, much appreciated. I absolutely love the lines and the design purity of the 1st model. If I ever get one, I'll make sure not to fire any hot ammo through it to preserve the frame.
Dobrý den, Mám dotaz (který je since kompletne od veci) jedna z podmínek ziskani zp je spolehlivost a za spolehliveho ze nepovazuje clovek který prokazatelne uziva alkohol Nebo jine drogy. Co to znamene v praxi? Kdyz sem treba v minulosti užíval marihuanu a muzu mit zaznam u doktora ale uz dlouho neuzivam znamenato ze sem nespolehlivy? Děkuji za odpověď
dobrý den, spolehlivost je narozdíl od bezúhonnosti trošku vágnější termín, a záleží na posouzení policie. Podle mě by to nemusel být problém. pokud jste pod vlivem neprováděl žádné neplechy a nemáte na kontě přestupek... Ideální je podat si na PČR žádost o ZP a uvidíte s čím přijdou

Awesome video, Amazing information! I wish I had them all!!!!
great stuff,
now i know where the DWX joke stems from
Always look forward to your videos. My new favorite CZ site!
thank you!!! :)
Thank you for the videos. I love my cz75 even more.
Glock 19X before it was cool. Perfect explanation😆
watched your cz75 videos great job
thank you mate :)

Just saying Hi!
Hey there! :)
It is called "lost wax investment casting"
Very informative channel. Keep up the good work.
Thank you sir
