Title: P06 .357 Sig
Post by: angus hobdell on January 18, 2008, 02:12:01 PM
New from the custom shop, the P06 in .357 Sig.
Since the Shot we have v ported the 5.75" barrel to reduce recoil.
Anyone going to Shot Show call by can see it.
Available with a  standard 4.75" barrel in Sig or have it in Sig and 40 S&W.
Hammer has been changed for Custom hammer and trigger work completed.
It's a  joy to shoot. Even at 1830 FPS

Very nice! CZUB has been experimenting with the .357 SIG for a few years. Glad to see them actually offer something, or is it a CZ-USA idea?

Can this be ordered?

I wonder where he got the .357 SIG ammo to get the 1830 fps number?

I've been a real fan of the .357 SIG round/concept for a number of years and still have an assortment of factory
and reloaded ammo left over from my attempt at converting a 75SA in .40 to the .357 CZIG pistol,
back when Bar-Sto was making barrels.

Given that this new P-06 is now available. MY choice would be Double Tap's:

3.5" barrel - 1415fps
4.5" barrel - 1525fps

Caliber : .357 Sig

Bullet : 125gr. Speer Gold Dot JHP

Ballistics : 1450fps / 584 ft. lbs. 4"bbl

PLENTY of power there! With low muzzle flash for the dark and scary encounters.
Something you really need with the .357 or 10mm.


I'll also note that in my area that .357 SIG ammo is quite cheap, in both JHP and
FMJ practice versions.  I see Winchester Ranger for $12 and below at most Gunshows.

Ammo was winchester from walmart If I remember correctly.
Thats what the chrono read you can see for yourself and I am very happy with the result from that brand of chrono.
This is offered right now by the CZ Custom Shop in Arizona, we can make the conversion on your gun or supply one I think we still have one in stock.
You would then have the gun in 40 and 357 sig

Cost depends on if you want the 4.75" shortened or left long and ported.
Contact me by email at the shop.

Howdy Mr. Angus,

I am with Mr. Mike, I would like to know if these 4.75" barrels can be installed in 40 cal 75B pistols too. If so I would like to get one for the 75B you did you action magic on for me, and pick up another 75B in 40 with your magic and the 357 Sig barrel. That would give me a pair to carry, which is my goal.

I did send you a pm at your store as well. Just want to cover all my bases, lol.

Howdy folks,

For those who have debated the 357 Sig round but never had the chance to try it in any platform before, I would really suggest you do so. Felt recoil is a very subjective issue to me. But I have some medical issues that on really bad days can directly impact on how long I can tolerate shooting. For me I have found that on those days, I can fire many more rounds of 357 Sig from various platforms than I can the same guns in 40 S&W. For me the Sig round has less felt recoil.

"Experts" attribute this in part to the fact the 357 Sig is a hotter load and tends to cause the slide to operate faster than the 40 round does. For me I tend to perceive it's recoil as more of a straight back rather than the more upward recoil I feel with the 40 round. But again that is really a subjective issue. But to date, without my mentioning felt recoil with friends and co-workers, I am always happy to let folks shoot my pistols. I start them with the 40 barrel, then change out to the 357 one. All shooters have said why does a round with higher muzzle velocity not seem to have as much recoil to me?

Another real plus to me is that I fell into a great deal on the .356 Speer 125 GD bullets, which is what the factory uses in their 357 Sig round. But I really hate to simply punch holes with that bullet too. Mr. Angus has a great deal on the Zero .356 125 JHP. I purchased 3,000 of those with shipping included. Shortly I will be trying some of those, comparing them to both my reloads and factory Gold Dots. When I can fire them over my chronograph I will post the results in the ammo room for those who might have an interest.

For reloading I prefer Accurate Arms no. 9 (now Western Powders) in this round. In their reloading manual they state this is the most consistent round they have ever reloaded, and speak highly of its accuracy as well. The fact it is a bottleneck cartridge is also seen as a plus in helping to insure reliable feeding too.

I don't want to hi-jack this excellent thread at all. But I just wanted to talk a bit about the 357 Sig round for those who have wondered if it was just all marketing hype or not. To me it clearly is not, but again that is a Ford-Chevy issue in my view too. But much like I saw the 10mm and its comparison to the .210 grain .41 magnum round, tell me I can fire a round ballistically similar to the 125gr .357 magnum from a 4" revolver barrel, and it does get my attention. Contrary to some comments I have read and heard too, this is my first bottleneck handgun round I have reloaded. I have not found any problems with it being a bottleneck round, and it loads identically to me as any other caliber I load.

The fact that Mr. Angus is offering any platform in this caliber simply makes me smile wide and realize that shortly I will be able to carry my pair of 75B 40s in a round that I have high confidence in as a self-defense caliber. Thanks Mr. Angus for being willing to offer this option. For those folks with a 9mm, I guess I could best describe this round as a 9mm type loading on very serious steroids.

Title: Re: P06 .357 Sig
Post by: cnw on January 13, 2010, 03:16:50 PM
Angus,

I have a P06, but have it FTF a lot.  I also have a Sig 229 and an FV 5.7 and love them.  No FTFs.  Returned the P06 to CZ with the hope they could correct the jamming.  No such luck.  My thought is that it is the recoil spring.  Ejects the spent cartridge, but cannot re-chamber the new one.

Two specific questions.  One, where can I get a new recoil spring, perhaps stiffer?  And two, how much is the .357 Sig barrel (or kit) for the P06?

Thanks,

Craig

This is a good combination for a CZ.  It has somewhat less felt recoil than a 40 S&W and has a superb down range performance.  The sales are not that good for most manufacturers for the 357 Sig.  However with the police and federal agencies adopting it, this should change.

I like my 357 Mag in. Colt Phython.  It never failed to do what I needed to do.  I would love to see CZ along with the custom shop start manufacturing a CA in a 357 Sig.  This looks like a win win with good marketing.
Title: Re: P06 .357 Sig
Post by: CPTKILLER on December 31, 2010, 03:58:54 PM
As a follow up to my previous comment, 357 Sig could fit well in the CZ lime up.  It works, it is accurate (reported to be better than the 40 S&W) and would work innermost CZ's that fire the 40 S&W without a lot of tooling or engineering design.

Here are some other's comments.

Okay I will pile on to keep this thread going. It seems as if it were done a while back but there is not much chatter on this conversion now.

Did anyone ever do the conversion?
Were parts ever available or is it only done if sent to CZ custom?

I have been thinking of a p01 but if I could have a p06 that shot both .40 and .357sig I might be swayed

Anyone have info?

I too plan on getting a 4+ inch (ish) CZ in .357 Sig. W/ Ameriglo tritium / fiber-optic front sights, and HD adj. sight in the rear W/ a single tritium vial in the back for the Str8 -8  or XS type sight pic. Hi Viz Day or night.

As far as I'm concerned The more, accurate the gun shoots, and the smoother, lighter, crisper the trigger W/O hurting carry gun reliability the better!

I'd rather get it like that Stock or as close to stock as possible, but Now if I gotta go custom then so be it.

Stuart:

When you say "THEY" do you mean CZ-Custom here in the USA?

Does anyone make a Hard (Gun Smith) fit Target grade thick heavy 9MM Bbl for a Cz pistol 

I like most of the P06 features ..  but really what I wanted was  a 4 to 4.5" Bbl Steel Rail frame, DA/SA Comp grade trigger, safety, no FPB feature, just like my 70 series 1911 except for the DA/SA trigger. but higher ammo capacity than my 8+1 SSTK, and shooting W/ a stays flat muzzle in the .357Sig. cal. and W/O the price tag of a custom.

Someone here was kind enough to tell me that I could get almost every thing I wanted out of the steel railed Cz 75 compact in .40 S&W then convert it to .357Sig. W/a BBl swap. so that's what I was going to do but... then I read here that the version I liked have been Discontinued,  :o ???

If that hadn't of happened then I was going to get the trigger reach reduction kit, Competition Hammer, and the best Firing Control Group micro - polished, trigger job 6#or less DA- under 3# SA  that I could have gotten done or just done it myself, then put in a Spring-co recoil reducer like STI runs,  and  then ...  big sigh

Back to the P06 I guess??

But I have a really hard time settling for an Alloy framed De-cocker - blocker model, maybe I'll be forced to go to a customized P06- Shadow Hybrid  W/ the steel Shadow frame, W/ the P06 .40S&W slide and heavy walled Hard fit 9MM Bbl reamed to .357Sig no FPB, ETC,ETC. I bet that will end up costing me way more than my 09 Dan Wesson custom 1911 and I'm sure it will more than double the cost of a used Cz 75 .40 steel compact or new alloy model .40 P06.. :'(

OH well I guess I'll just be sitting back and contemplating for a while to see if I can find a used Discontinued model or to see what happens W CZ bringing it back into production....

Sorry but I'm long winded thanks
Title: Re: P06 .357 Sig
Post by: Stuart on May 02, 2012, 03:30:15 PM

CZ custom will chamber for the .357 SIG.

its cost of a new barrel, rechamber the barrel and fit the new barrel about $375 for the conversion.

My Sig 226 came as a 40 S&W but they sold me a second barrel for the 357 SIG for only $175.  I use the same mags.  If you are intrested, the 357 round is a fair bit snappier than the 40 S&W, even in a full-sized pistol.

Or is that too easy?

Thank you very much Stuart you have eased my mind a bit.

So Stuart plz tell me what do you think the game plan would be?

do you think they'll Maybe use a Shadow rail frame and pair it W/ a P06 or PCR? top end, I cant remember Which is which but  I really like the tri topped slide look as long as I get a true 4"-4.5" Hard fit target grade BBl, and an equivalent Trigger job W/ it I'm sure I'll like it.

not sure what  you mean by the gameplan?

The shop can do the conversion to most of the .40 cal guns. been done to several P06 guns, Tactical Sport. Should be doable to the SP01 Tactical in .40 and the discontinued .40 compact.

Angus-
There have been comments that the 357 sig is more accurate than the 40 cal, other things being equal.  Is the rate of twist greater in the 357 barrel?  Could that be pertinent to the greater accuracy?  Thanks.

Does the only necessary change involve the barrel?  Or are new springs required?  Do the same magazines fit the 40 and 357?  Sorry for ignorant questions . . . have not actually seen and compared these two rounds.

I'll add my voice to this one!  There is no reason that CZ can't put out a .357SIG barrel to purchase as a swap out part, except that they seem to be very closed off to customer input.  I'm not talking about CZC(Angus's Shop), but CZUB proper.  There is a sizable, not huge but sizable, market here in the US for those that own a .40 solely to have the ability to easily swap out to .357SIG and back again!  Currently that market is dominated by Glock and SIG Sauer, but as fast as CZ is growing here (the lack of availability for many models being proof of that) there is no reason that they should not be able to offer what their competitors have for a long time now. 

I LOVE CZ's and have definitely been bitten by the bug, but some of their decision making on products baffles me. 

Also, they need a US plant to make their product more available and so that they can compete in the Army's new Pistol trials!  Perhaps with a more ergonomic CZ 97D Compact with 12+1 capacity?

FYI, it's not just Sig and Glock - Springfield has an XD in 357Sig (both in 4" and 5" varieties), and/or you can order a 357Sig barrel for your XD40 directly from Springfield.

Hello All,
Is there anyone that has done this recently or has any information on this. I would love to add a 357 sig cal CZ to my family instead of bring in one of those other pistols that shoot the same round. ;-) I am becoming a CZ Snob, but in a nice way. It all good if you like that other stuff. I prefer what I prefer.

I just made a 357 SIG barrel for my P-06 this last week.
I test fired it Saturday.
I did go to gunsmithing school 30 years ago so I am a bit above amateur, but it wasn't too hard.
I was able to do the work on my beat up old Atlas 12" lathe, with a 4 jaw chuck..

I started with a 9mm barrel for the P-01 or PCR.
I got the chamber reamer from Brownells on sale for $60 and the Go/No-Go gauges from Manson for $30 each.
You have to be very careful when reaming the chamber.
It is very very easy to go too deep and destroy your barrel.
To get close on the lathe I measured how far a 40 S&W cartridge stuck out of the breach end of it's barrel and used that as a target for my barrel.
Once I was getting close a had to pull the barrel from the lathe, assemble the gun and try the Go gauge.
The 3rd time it locked up perfectly.

The trick to using a 9mm barrel is silver soldering on a collar to index on the larger barrel bushing on the P-06 slide.
The 9mm barrel is 0.500" OD exactly, while the 40 S&W barrel measured at 0.544".
I wanted to see how tight I could get the barrel to the 0.552"ID bushing so I made it too tight and them stepped it down gently until it fit perfectly at 0.549".
The collar is 0.675" long and tapers to the muzzle.

The only issue I had at the test fire was the Speer Lawman 357 SIG ammo was a tiny bit too long for the CZ mag and tended to drag it's nose as it fed.
This led to many jams until I learned to make sure I seated the ammo all the way in each time, then it fed fine.
I will be hand loading for this and can manage my OAL precisely.
Recoil was about 10% stronger than 40 S&W from the same gun.
Accuracy was stellar.
I'll try a stronger Wolff spring to see if it cycles a little smoother.
 
Overall I am very pleased with the outcome.

Interesting approach. CZ Custom uses an SP-01 9mm barrel and fits it by removing the extra lug and cutting to length.

I would like to shoot a 357sig.

I just noticed this thread (I'm a noob here) but I'm a big proponent of the 357 Sig cartridge. I have Glocks and SIG-Sauers that shoot it and would love to have a CZ that did, too. Not that there's anything wrong with 9mm, but it's always nice to bring a little more power to the party.

Now is this a unicorn item, or is it actually available for sale somewhere?

I would like to shoot a 357sig.

I haven't shot my M&P FS .357 SIG in a couple years.  However, last time I did (still just shooting it to make sure it was going to keep working - functioning issues - timing and sear bounce - that were tough to diagnose and not to hard to fix - but unsure they'll stay fixed, so I don't rely on it) I put about 150 rounds through it.

Then I got my new P09 9MM out and we started to shoot it.  How did shooting the P09 9MM "feel" after shooting the .357 SIG?  I knew the 9MM was firing.  I could hear it.  I could see the bullet holes in the paper.  I could see the empty cases on the ground to my left.  But the recoil was so light I kept looking at the first 3 indicators to assure myself the P09 was really firing.  It felt like shooting a darn .22, almost.

I will, someday, have a reliable and accurate .357 SIG.  My Glock and M&P don't meet both of those criteria and reside in a my gun safe these days.  I've got a P09 .40 S&W I keep thinking about sending in to get a .357 SIG barrel chambered/fit to the slide.  We'll see.

IF anyone EVER figures out where to get a .357sig barrel for a P06, PLEASE let me know!   That's my preferred round. :-)

My .357 Sig is a Sig Sauer P226 Legion.  I didn't expect CZ to ever come out with anything in that caliber.

A side bonus is that by simply swapping barrels ($295 from Sig) it also fires .40 S&W.
