installed a 357 barrel in my P320c
I posted this in another forum earlier today.
A couple weeks ago I traded a 9mm P320c that I'd had some issues with for a P320c in 40 S&W. Then I promptly ordered a 357 barrel from Sig. That arrived yesterday, so I took it out this morning to run some ammo through it. I chrono'd 4 different loads. Here's the the 10 shot averages:
Gold Dot 54234 - avg 1278 (a little disappointed with this one)
Federal HST - avg 1321
Remington Golden Saber bonded - avg 1330
Speer Lawman - avg 1246
The HST and Golden Saber velocities were what I expected from 357 Sig in a compact barrel. I've got other boxes of Gold Dot with different lot numbers. I'll test those and see how they compare. The gun performed flawlessly, and was very accurate with 357. Recoil was about as heavy as 180gr 40 S&W, but less than 165gr Lawman.

For mine, I got my .357 SIG compact barrel from Sig directly about 1 month ago. I called them twice before ordering to make sure and they confirmed that the .357 SIG compact barrel is compatible with both the P250 and P320 (was not listed on website if you search P320 compact barrels). I've shot approximately 300 rounds of Speer Lawman 125 gr range ammo and it's been flawless (https://www.sigsauer.com/store/barrel-p250-357sig-compact.html)... this barrel actually is showing zero wear so far. Love the round in my VP40 and now in my P320C!
Now I just need a P229!
By the way, the Speer Lawman .357 SIG 125 gr FMJ ammo for range use is a no-brainer IMO at 0.29 / round !!! (https://www.targetsportsusa.com/spe...25-grain-total-metal-jacket-53919-p-1096.aspx)
.
I called Sig support because I didn't see it listed on their website. It was back ordered, but it only took 2 weeks before it shipped.
I looked for a P320c in 357, but couldn't find one. So I decided to start out with a 40 and add a barrel in 357.
Same for me. My 357sig barrel took about 2 weeks. I still have yet to get it to the range.
