I don't know yet.  I have a 357 Sig barrel coming for my 75B and I can let you know after it arrives and I get a chance to shoot it.

I have a custom Fusion firearms 1911 , 5 inch and my son has a Sig 229 as well both are in .357 Sig, I love the caliber and performance. Both are fun accurate shooters. I also enjoy 10 mm. the downside of both of these calibers is the higher cost of ammo. I would like a Cz in this caliber as well,I have looked at what CZ Custom has to offer and I like it. I have one on my list of firearms that I plan on buying.

Have a SIG 226, 229, 1911 and a JRC (Just Right Carbine) in .357 SIG. I love the cartridge for both it stated power numbers and my real world experience of its accuracy potential.

I am not a reloader (however I save my brass) but from my reading, I find it is not the friendliest caliber for the reloader. Of course it is more expensive to shoot than some others. I think the least I paid (for 1000 rounds) was $0.29 per round. Close to .45 ACP prices but you don't seem to find deals in .357 SIG like you can in .45 ACP on occasion.

I got this from another forum - but it works.

Use a .40 S&W carbide die to resize the .357 SIG brass first.

The run it through a standard .357 SIG die - without sizing lube.  The neck and shoulder are such a small area that as long as the body is already resized the std. .357 SIG resizing die will take care of those areas just fine/easy.

After that, it's just belling the case mouth to accept the new bullet, putting the primers in, adding powder, seating the bullet and crimping - all done the same way as any straight walled case.

I did run into an issue earlier this year (or was it late last year??) where I was tearing up some of the cases.  I'd get that dreaded bulge right at the transition from case side wall to shoulder due to some brass being longer than others and then the die bulged the long cases when crimping them.

All I was doing was removing the bell/flare on the case mouth but the longer cases where getting really pressured by that step in the die that crimps/removes the bell in the case mouth.

Neither my Glock M31 or my full sized M&P are much for shooting good groups and I stopped shooting them when the CZ's spoiled me with their accuracy (9MM and .40 S&W).

I like the caliber and it's potential, I just want a pistol that shoots good groups.  Be sure, Timetofly, to come back and show us some groups.
I stopped carrying the SIG 556R.  SIG changed models and couple/three times and stopped supporting it with parts.  So, I stopped supporting SIG.  Back to the tried/true AR15 Carbine.

I had a Sig P-226 with a .40 slide that I fitted both 9mm and .357 barrels to.  I loved shooting that pistol with the .357 Sig barrel. 
Texas State Troopers carried them for years, I think in the 90's, not sure. 

It was a fun round, but I never shot the .357 barrel enough to really become proficient with it.  The 9mm Bar-Sto conversion barrel worked perfectly in that pistol.  I put a red dot on it and used it for a backup bullseye gun when the P-09 was my primary pistol.  Never needed a backup, so I sold the P-226 with all the barrels and magazines to a friend of mine who uses it for his backup gun. 

From what I remember, recoil was substantial, and followup shots took some effort.  Not exactly a bullseye friendly round with factory defensive loads (single hand standing).  But fun to shoot.

You can count on a report on how I like the 357 Sig.  I've been curious about the 357 Sig for a long time.

I always get a kick out of the guys that holler a .357 SIG is not big improvement over the 9MM and then later recommend 9MM +P or even +P+ ammo to gain extra velocity.  That's what the .357 SIG is - extra velocity.

A steady diet of +P and +P+ 9MM ammo isn't good for the pistols most of us carry.

I picked up a new Gen 4 Glock 31 today, and my order of Underwood ammo also showed up. I will post my thoughts after I get to the range.

It's a novelty round for me as I'm not sure it does anything that a 9mm of 40S&W cannot do in self defense. With that said, I like it for the accuracy and high velocity "crack" that it produces. It is a lot more damaging to plinking targets. I've had excellent results with AA#7 and 125 grain bullets. I have not had good luck with 147gr projectiles. My favorite load is 11.4gr of AA#7 and a 125gr Gold Dot. That load is above the current Accurate powder reloading document but was allowable in previous versions. I use 10.5gr for practice loads. Currently I am just shooting them in all Stainless SIG P226 platforms, but I have a 40S&W SP01 and fitted a 9mm barrel to it for 357SIG conversion. I just need to get someone to cut the 9mm chamber to 357SIG for me.

I have a P-320 in .357 Sig. My favorite semi-auto round. I may try to obtain a 75B in this caliber..

I think CZ Custom can convert your 9MM barrel to .357 SIG.  Maybe Cajun Gun Works, too.  But CZ Custom had a video out a few years back of a Tactical Sport .40 with a .357 SIG barrel and it was a pretty awesome video.

I'm still trying to figure out whether to keep my CZ75B .40 a .40 or get a barrel for it.  It's doing pretty well (group size) and I hate to mess with a gun that shoots to suit me.  Just have to concentrate on it long enough to make up my mind.

That would be the 38 Super, but you keep thinking that.

I've never tried one, so I don't know if I would want .357 Sig barrels for any of my .40 CZ pistols.

The only times there were ever .357 Sig pistols fired when I was at an indoor range were the days I was trying to pick up my 7.63x25 Mauser, 7.65x21 Luger or 7.62 Tokarev cases.
