I don't own a firearm chambered with the 357 Sig but have been thinking about buying a barrel in that caliber for my Glock 26. As the 357 Sig is just a 40 S&W necked down to 357 all the conversion requires is the new barrel and maybe a heavier recoil spring thought all I have read just mentions the barrel. For around $100 you have one gun in two calibers. That appeals to me. ( I know, I know...... "this is my rifle (or pistol), this is my gun. this is for fighting and this is for fun. been there, done that)

I have no experience with .357 Sig. I have been curious about wear and tear on the gun. If using the same frame with .357 Sig as with .40 S&W, does the .357 Sig cause more wear on the gun?

Only real drawback is lack of a cheap source of ammo.

Bottleneck pistol cartridges are a pain in the ass to reload. The 357sig makes it in the same difficulty as the 458 socom due to the super short shoulder. Screw up setting the dies and you ruin a lot of cases which arent easy to get.

Then they gotta be trimmed to length each time.

Not an economical round if your not using ammo paid for by the blood sweat and tears of taxpayers

I like the 'concept' and this is a good defense caliber. But there is no 'need' for it. It is the ballistic twin to the 357 Mag. (125 gr bullet 1250 to 1400 fps). I shot a 9mm with +p+ ammo which is clocked at 1285 fps. Both are '357 Mag' ballistic twins but the 357 Sig does it without +p rated ammo.

What about a permanent wound cavity, ballistically, is it much better than 9mm +p+?

No they are not. That is point. It has been found that the 1250 fps (.355/.357) is all you need to achieve the 'maximum' possible effect on an aggressive human animal. Anything over this velocity (1250 fps) by a bullet of .355/.357 diameter in the 115-130 gr (JHP) range is 'over kill' thus the very slight difference in the wound cavity has no realistic advantage.

I love that explanation, thank you very much. My next choice is to check out a 10mm... I've shot one a couple times (rented a G20 twice), it felt great, but I'm really more interested in the 29...

I pay about $16-22/50 for range ammo, which ain't cheap. Defense ammo is affordable enough, as Winchester Rangers or Gold Dots can be found for $25-30/50.

High performance round, but expensive. 9mm and 40sw are both quite a bit cheaper to shoot at the range, and both have defensive loads (9mm +p+, 40sw in 135-140gr CorBon) that really aren't that far off 357sig ballistics...so that's sort of a counterpoint.

I like 357sig and sometimes carry it in the woods. But I primarily shoot and carry 9mm and 45acp otherwise.
Whoa whoa whoa...you're saying that $16-22 ain't cheap for .380, .40, .45, or anything similar? Please let me know where you're getting your range ammo, cause even before this latest ammo crisis, I have never seen range ammo (brass) in either of those 3 calipers cheaper than what you said. 9mm on the other hand, yes. This time last year I could get a decent 50 round box of 9mm for anywhere from $8-12. But not for .380, .40, or .45. And most of your popular revolver rounds that I've seen are even worse.

.357 Sig, .38 Super & 9 mm +P (+p+) are all close enough in performance it becomes down to splitting hairs or urination distance. So many other variables are important. I can't imagine anyone saying after a shooting incident, "Golly that extra 90 to 100 fps would have made all the difference." IMHO, placement matters much more than minor velocity differences. I suspect that over penetration isn't really that big of a deal with proper bullet selection.
I see .357 Sig as a boutique round that's used mostly by people who who's ammo is "issued," courtesy of taxpayers. IMHO, it's not enough of an improvement over hot loaded 9 mm to warrant any special consideration from those buy their own ammo.
If you think it's cool or want it because it's different, great, enjoy. Just don't think that it's next big thing in SD technology.

If I want a boutique cartridge, I'll hunt down a 10mm. It's easier to reload and range brass is more common.
