Title: 357sig in a P-07?
Post by: goosedowner on March 07, 2015, 04:57:20 PM

I love the 357sig and I was wondering if you can convert a 40 cal 07 over? Who would make a barrel for this?

Good idea!

It would appear to be an easy swap. 
I bought a $169 barrel for my Sig 226 and can now use the same gun for 40 S&W and 357 Sig.
No reason that CZ can't do the same.

What little I (think) I know is that CZ doesn't make a .357 SIG P07/P09.  They don't make .357 SIG barrels for the pistols.  The 9MM P07 barrel (even if rechambered to .357 SIG) has a different width barrel hood than the .40 S&W barrel so the rechambered barrel would be sloppy in a .40 S&W slide, unless the hood was modified in some manner.  A P07 9MM slide would have to be modified to allow a .357 SIG round to fit against the breech face, chamber in the barrel.

And even then, if work was done on a 9MM slide to allow the .357 SIG case to fit/feed/eject, etc. the extractor angle/fit might not be right.

The best fit would seem to be using a .40 S&W gun, with a barrel made for .357 SIG.  But I can't find anyone making one.

Not sure what it would cost to have a 9MM barrel rechambered and the barrel hood modified to provide consistent/even fit in the slide.

I'd like to have one, too.  That was my idea behind buying that P07 in .40 S&W.  Then, however, it turned out to be the most accurate of all the many brands/calibers of polymer framed pistols I own and I will not mess with it.  I may buy another one some day, and have it messed with, but not that first one.

CZ Custom was doing 357 Sig conversions on the P-06 and some of the full size CZ 40 S&W modles. I have not heard of them doing a P series but i might be worth a call to CZC.

I'm curious if there is any information on this

I would imagine if they make them for a P09 then they would for a P07.
 I have one being done for a SP 01.

Should be no problem to modify a 9mm barrel for a 40 gun.

Would the P07 frame hold up to the pressure? I've heard of the cracking issue.
