CZ50/70 Barrel Removal/ Swap
« on: January 25, 2017, 11:02:38 AM »
Hello!

I?ll ask my question first and then give the back story if you?re interested.

How do you remove the barrel of a CZ50/70? I know there is supposed to be a barrel pin somewhere but I?m dammed if I can find it. I purchased a used barrel but it doesn?t have a slot cut for the barrel pin or a slot cut out for the extractor. I planned to locate the pin using the used barrel. Also the breach seems to have a step up and is not smoothed. Does this sound like it?s possibly a new barrel? Any help you guys can give me would be appreciated.

Now here is the short version of my CZ adventure so far?
   After several years of prodding, I finally talked my step-father into selling me his CZ50. Out of all the ones I?ve looked over it was pristine. He has a bit of OCD and his collection shows it. So I was eager to take it off his hands. This was to be my first CZ. TO keep this short, the first range trip I got a total of 2 shots from it before I got the dreaded locked up slide. The slide seized as it traveled forward. It would not move either way. On closer inspection I found that the barrel had bulged. Now this could have been due to the ammo as it was suggested that I had a squib on the first round causing the blockage prior to the fatal round being fired. Either way, after to separate gunsmiths told me it was a total loss since there was no way to get the slide off or the cost of their time far outweighed the value of this out dated relic. I decided to have a go at it. Over a couple of months it looked bad as I couldn?t see how I would remove the slide since the bulge was between the end of the slide and end of the barrel. With the help of a rubber mallet, a piece of leather, a deep well socket, two zip-ties and a handy hacksaw I removed the bulge and 1 1/2:? of the barrel that allowed the slide to come free. So I then had a pristine saw off CZ50. Even though that sounds cool to some kid, not so much with a semi-auto pistol...

Thanks, I've read the other post with the bulged barrel as well.
I'm still trying to locate a text document covering disassembly. The pictures don't really help.
You see, I'm just an old blind Marine that still likes a challenge.

I spent some time scouring the Internet looking for a text document as well but could not find anything.  The best  information out there that I found was not printed at all.  It was an e-book with detailed photos. Lgrlik posted one of the photos from the ebook. The ebook has many photos and detailed drawings and is worth the $6-7  I paid for it.  The retaining pin is a blind pin that you cannot easily see. It is, however there as depicted in the drawing.

The pin is very much blended in and the pic above is the one to drift out. It's in there very tightly. An arbor press is your best bet.
