Wanted to ask the brain trust here if anyone has heard anything about SIG offering the P365 format in 357Sig caliber in the near future.

I love the different P365 product offerings and it is my format of choice for concealed carry. I read the thread related to the 357Sig round and now I am wanting to add it to the calibers I shoot and reload.

Thanks in advance for any replies.

I'd want to see a larger, compensated 365 in 357SIG myself, but that's just me - the more I've shot a gun at the range recently, the more confidence I have in my ability to use it for self-defense.

There may be a bigger problem than me being a recoil wimp, though. When the 365 first came out, the big selling point from SIG is that they managed to get as many rounds of 9mm into as small magazine as they did. I'm not an engineer (and don't play one on TV), but I wonder whether redesigning the magazine for the larger-diameter 357SIG case would take a lot of work.

Considering Sig offers no current production handguns in .357 Sig any more, with no plans to either, the chances of a .357 Sig P365 are basically zero.

Unfortunately.
But because of the changes in the gun and magazine that would be necessary for the larger, more powerful cartridge (I believe), would it still be a P365? Or would it be a P366 (extra power for a longer year )?

Although I am a fan of the 357 SIG, as I have discussed elsewhere, for any number of reasons that is not true of most of the potential users of such a gun/cartridge combination who are fully satisfied with the 9mm Luger round.

Great point that I did not realized.

We're more likely to see a P365 chambered in .30 Super Carry than .357 Sig.
I wouldn't bet on either one coming to market - ever.

As an AVID 357sig guy, I think it's dead.
I still have a few guns in it but don't shoot much. I do have a few thousand maybe 10k rounds in storage. when we switched from 357sig to 9mm at work, the chief was like i don't want the liability of selling the ammo, dispose of it however you want, so i disposed of all the remaining ammo into my car.

I might send off my old duty gun for porting but I really don't want to. I had the slide down over by maple leaf and nitrided. and my 33 slide is engraved with dept patch and CPII by CCR. I might have to pick up a 32 I guess. My other 357 is my old HK usp c.

with USSS moving from 357, that is unlikely.

I'm trying to imagine the snappyness of a 125g gold dot in the X Macro . Even my SP2022 is a beast but I was a weaker man the last time I shot that. Most of the reason I see 357 SIG, and 40 SW for that matter, on the outs is recoil management and accuracy and trading ballistics for capacity especially in these micro-9s. If I ever saw a CZ RAMI in 40 it would probably be mine .

357's a great round though. not the easiest to load I imagine. I wish I was asked to dispose of a few cases. As we all know, the best ammo to shoot is OPA


My favorite 357 Sig system.

Thanks guys for all of your comments and feedback. By reading these posts my best bet is to find a good P239 in this caliber or just purchase a 357Sig barrel for my Sig P226 all stainless pistol that was born as a 40cal.

To change this thread direction a little bit - Any advantage of purchasing the Bar-Sto stainless 357Sig barrel for my all stainless P226 over the SIG factory OEM blue steel barrel?

It’s been a long time since I’ve seen the question of Bar-Sto barrels versus factory parts discussed here, but as I recall, sometimes the Bar-Sto require a bit of fitting. But perhaps that may refer to only their “match” versions. In any event, I’d probably check if it might be important.

I have multiple factory 357 SIG barrels and only the first that was swapped into a 40 P229 by the gun store where I bought it was a little tight. After firing 50 or so rounds, it was fine. I have been perfectly satisfied with all the factory barrels I own, but I never expected 1" 50 yard groups either.

I bought a spare 357 barrel from SIG a few months ago “just to have” before they dry up.

Added: You should confirm for yourself, but the SIG site no longer shows 357 SIG barrels for the P226.

Sigfreund - You are 100% correct related to your comments about the Bar-Sto barrel. They sell two different barrels and the standard barrel “will”require some fitting. Being that I am not a gunsmith by any means, I am going to go with a factory OEM barrel. In fact I may do what you did and order an extra one because I have no intention of ever selling this P226 all stainless pistol.

Thank you again for your comments and feedback in this thread. Greatly appreciate your help and guidance.

All the best for your journey.

SIG pistols in 357 have been my handguns of choice for decades and if I weren’t so old, I would be berating SIG for abandoning the cartridge that they were responsible for developing. As it is, I probably have enough guns and ammo to keep me going for the rest of my life, or at least for as long as I’m able to use them.
(Assuming the wildfire a few miles away doesn’t force me to leave my house to let it all burn up.)

The comments on Bar-sto barrels are spot on. Their MT (Match Target) barrels always need fitting. Their SF (Semi-fit) barrels may or may not need fitting (mine did). Sometimes the owner can do it themself, though I decided to just send it back for "pro" fitting.

Since I don’t believe there was ever a P365 in .40. It would take a bunch of redesign to make it .40 or 357 SIG. New breechface for one.

Sig was always big on designing a gun to shoot .40 or 357 SIG. Not just putting a new breechface and barrel on an existing 9mm frame, like Glock did. Both my .40/357 SIG P239’s have markedly heavier and talker slides. As do my P250’s. The P229/P228 was re engineered to shoot the .40/357 sig. heavier slides and recoil springs.

I don’t think here’s enough slide on the P365, even if they leave out some machining, to make it heavy enough to handle the .4/357.

I’m also not sure the frame would take it for any length of time.

Sig put their own 357 Sig cartridge on an ice floe and pushed it out into the Arctic Sea.

If you’re considered to be useless—whether true or not ....
And of course it was the “good enough” crowd that made that decision.

No they will never chamber it in that. It’s purposely built around 9mm and chambering it in 40 and 357 would mean a new pistol.

Not to mention, Sig doesn’t offer anything in 357 these days.

Perfect is the enemy of good enough.
