P229 = 10mm

I have a P229 in 40S&W, I know I can get a 357Sig barrel for but I don't remember hearing anything about a 10mm barrel for it. Has anyone done this.

You can go the other way probably. From 10MM to 40,357 sig. But not 40,357 sig to 10MM.
And 10MM was never made in a P229 platform. 10MM was only made in the last few years in the P220.

Yes, I know that but a 10mm barrel is really just a 40 barrel with a longer chamber I believe. Like the 357/38 revolver cartridge. So I guess my question is does anyone make the barrel and has anyone done this.

I don't believe the length of the action is sufficient to run the longer 10mm round. Grayguns had a difficult time adapting the larger P220 to the 10mm cartridge.

OK, that would explain why their aren't many handguns chambered for the 10.

Other Jim has it.
10mm Norma requires a .45/.38 Super length action and magazine. Wouldn't hurt if it were a little longer than that, but nobody is going to tool up for a pure 10mm after the Bren Ten fiasco.

That leaves you with P220, 1911, Glock 20, and large frame Tanfoglio. A CZ97 10mm is rumored but seems to be a custom conversion from .45.

P229 40SW and 357SIG can be just as Powerful as a 10mm Auto with the Right Ammo

The P229 is a Small format Pistol for Sig that is only available in 9mm, 40SW and 357SIG! If you want 10mm Auto you have to go to the Large Format which is the P220 which is available in 45acp and 10mm! One of the BEST LOADS for the P229 in 357SIG is the Underwood 125gr Bonded JHP with a Muzzle Velocity of 1475 FPS and Muzzle Energy of 604 Ft-Lbs. The Recoil of that load is very Manageable even during a Quick Double Tap! I did Swap OUT the Hollow Guide Rods in my Sigs for Solid Stainless Steel Ones that ADD a little weight and I also changed out the Recoil Spring to the Next Stronger One by Wolff Springs the Factory Spring is 17LBS but I swapped it to a 19LBS to Reduce the Felt Recoil.

Technically the P229 is available in 10mm since the 40SW is a Weaker powered version of the 10mm Auto but you can get the Underwood 135gr JHP in 10mm Auto Muzzle Velocity is 1600 FPS and Muzzle Energy of 767 Ft-Lbs and 40SW Muzzle Velocity is 1400 FPS and Muzzle Energy 588 Ft-Lbs.

I currently several P229s with and without Rails including a couple of German made ones in 357 Sig, 40 SW and have a 9mm Custom Shop Elite on the way plus P226s in 9, 40, 357 as well as P220 in 45 and One P220R 10mm Legion. The P229 was DESIGNED and Build to be a 40SW/357SIG and not a 9mm that just got a new barrel and recoil spring.

When ever I purchase a 40SW or a 357 Sig I like to get the 40 or 357 barrel so I can shoot the other caliber as well because that way I can shoot the weapon with which ever ammo is widely available at that time.

Last year I purchased my first Large format Glock a Model 41 45acp and a model 21 45acp but since those Glock pistol have the ability to swap barrels I can Also Shoot 10mm Auto in those Glocks.

That leaves you with P220, ...
For the OP, also note, SIG only chambers their 10mm P220 in steel framed models. I assume they have a reason for that.

OK, where is the best place to get a 357sig barrel. I want to get the best one, not the cheapest.

A very good reason for that.

The P220 Frames that Sig is using for the 10mm Auto Pistols are STEEL Frames NOT Aluminum Alloy because of the Recoil Impulse of the Full Power Load of a 10mm Auto is Allot more than a 45acp and the Aluminum Frame would have had a VERY SHORT LIFE CYCLE!
I have a P220 10mm Legion and it is heavier than my Sig 1911 TacOps 45acp 5 inch barrel! The 10mm P220s have Thicker Slides and Frames to take the Abuse of the 10mm but also reduce the Felt Recoil! The first time that I shot my Legion which was the first time I shot a 10mm I was surprised how manageable the recoil was! Sig did a GREAT Job Engineering the P220R10s specially that captive recoil spring which seems very heavy when you first try to Rack the Slide but make the Recoil feel like you are shooting 230gr Ball FMJ out of a 5 inch 1911 with a 18.5LB recoil spring and I can do that ALL DAY Long and Have!

The 10mm cartridge has an OAL of 1.275" nominal. It will feed through any pistol that feeds .45 ACP or .38 Super.
The .40 S&W has an OAL of 1.169" nominal. I was designed to fit and feed through 9mm size pistols, after the politically driven FBI waffled all over the place blaming the 9mm for agency protocol failure, went off the deep end adopting the 10mm, the quickly backtracked to a reduced load 10mm of approximately .45 ACP power. Smith & Wesson was quick to capitalize on the reality that one doesn't need a 10mm length case to push a 180 grain bullet at 980 fps, and the .40 S&W was born!
The .40 S&W is indeed a positive step UP in power over the 9mm. It pushes a larger diameter bullet, a heavier bullet, and is easily capable of generating over 550 lb-ft of energy in the heavier weights, and well over 600 lb-ft in the lighter weights. A 155-165 grain bullet can easily go 1,200 fps which clearly exceeds the 9mm - as was the original intent.
Heavy bullet 9mm loads of recent design have shown impressive results in blocks of dangerous ballistic gelatin, prompting the FBI to disavow the .40 and scramble back to the 9mm - probably because the stats indicated little difference in the response of actual humans hit, and due to changes in how officers are trained to shoot - meaning, shoot early, shoot fast, shoot a lot, and shoot until the threat ceases to be so. Three to five, to 15 shots of 9mm fired into someone quicker than the ear can detect the report will tend to do just as good a job as 3 to 5, to 12 shots of .40, or 3-8 shots of .45 auto.

The Sig P229 is a "9mm length" action and so cannot accommodate the 10mm - it's not about the chamber, it's about the magazine length front-to-back. Sig does do an excellent job of making .40 barrels that are fully supported which means one can shoot top-loaded Underwood ammo without worry, or hand load into the lower end of 10mm power.

The .357 Sig is exactly what its name states - a .357 magnum "squoze" into a 9mm length case! The upside is that in the lighter bullet weights the .357 Sig is on par with the .357 Remington magnum revolver round and VERY impressive in gelatin shots! The downside is one gives up 2-3 shots due to the bottleneck case design, and I suspect this has done more to put-off buyers who tend to be "capacity conscious" in the 9mm bore size.

As for the 10mm mythology that just keeps going around generation after generation, the company who really kept the 10mm alive wasn't Colt with their overpriced, and under-engineered Delta Elite, nor S&W with their limited offerings of converted .45 autos. It was GLOCK who jumped into the deep end with the G20 despite proclamations of the 10mm being all but dead and buried. Perhaps Colt, S&W, Sig, and other "metal frame" gun makers can't figure out the "riddle of steel" to build a handgun capable of holding up to routine use with full-power 10mm loads, but apparently Glock figured out the right type of PLASTIC to use! Glock's "plastic frame" 10mm was and still is reasonably priced, lighter than any other brand, and holds a solid 16 shots of 10mm! Going a step further, Glock's G29 is truly SMALL, and holds 11 shots of full-power 10mm! Then came the G40 - Glock is now fully supporting the 10mm across three different models which is 3X more than anyone else, and all are based on "plastic" frames which have proven to be more durable than the far pricier steel frame guns.
