CZ 75 B 40 S&W - 357 Sig

[wgg]

I am looking at a CZ 75B for the purpose of converting to 357 Sig.  I am not having much luck locating a barrel.  Is this something I should skip.  I like the 357 cartridge, I have a Sig 226 DAK. The CZ 75 and the 1911 are my favorite pistols.  Thanks Glen

First off I have no idea what I'm talking about here. But couldn't you rechamber a CZ 9mm barrel to 357 Sig? The 357 Sig is just a necked down 40 S&W to 9mm. If it's possible you'd probably have better luck finding a 9mm 75 barrel than a 357 Sig barrel.

From what I have been able to read it would take the 9mm barrel for the SP01.  The barrel diameter for the 40 S&W is larger and the SP01 barrel is the proper diameter.  I have sent an email to CZ Custom. I believe I read where they have done this before.

That's the way to go.  I think you're right as others have had it done in the past.

CZ Custom responded, they can order a barrel and chamber it for 357 Sig.

I went ahead and picked up the CZ 75B 40S&W.  Very nice condition with 3 magazines, the case and paperwork.

Where did you get it from if you don’t mind me asking ,are there some more ?

I picked it up from a fellow, that offered it to another fellow in response to a wtb add.  He wanted a 9mm model.  I have been looking for a CZ75 in 40 S&W for a few years. So I contacted the seller and he made me a good deal.

I ran across mine mostly by accident 2 or 3 years ago.  I only shot it a little bit before sidetracking myself about another gun or three.

Darn thing shoots so good I would not convert it to .357 SIG.  Had it been a pretty poor grouper (like my 4" FNS .40) I'd have followed up on the .357 SIG conversion.

I love the look of the .40 slides, too.  They look like the CZ75 SA slide, with the full length rails.

Good luck with your conversion.  Pay no attention to the people who tell you that the extra velocity of the .357 SIG is unnecessary in one thread and then, in another thread, tell you to get/shoot 9MM+P ammo, for the extra velocity.

Can't say it's true buy I've read, a few times, that the shape of the case makes the .357 SIG feed better than a straight walled case.

I will say, if you reload it, you may find a need to trim cases for length (you don't have to do that with straight walled cases.)  Not trimming may lead to crimping uniformity issues which cause other problems.

There's a video, on you tube of a CZ Tactical Sport CZ Custom fitted with a .357 SIG barrel.  It's some pretty awesome shooting/velocity.

I converted a SP-01 with a CZ75 40 S&W Slide to 357 SIG (kept the 40 cal barrel too). I had a 9mm SP01 barrel bored/throated by CZ Custom and machined the lug off and fitted it myself. The 357 SIG round is an interesting caliber for me, but I wouldn't feel uncomfortable with a 9mm or 40 either.

I have a Sig 226 in 357 Sig.  I was issued it by my agency,  they allowed me to purcase it upon my retirement.  I have a stock pile of ammo, so I am familiar with the cartridge.  The 357 Sig is an impressive cartridge.
 I carry a CZ 75B 9mm for a duty pistol.  This project is something I have wanted to do for years.  I could not find a donor.  I have dies coming for the 40 and I will play with that round as well.

They are harder and harder to find, I assume not that many were made or people just hold on them.

Now that's a pretty pistol.  What type of finish does it have?

[huskerlrrp]

Hard Chrome from Accurate Plating and Weaponry and the TiN from Brazen. Initially I did the TiN on action components to see if it made any difference (honestly I can't tell) but I have found the barrel is much easier to clean with TiN and I also get a little respect from the pimps when I'm carrying it around.

Love it
