I have, and carry, both.

I have had both and I think that I'd rather get a glock in 357sig because of the reliable feeding, higher cap, and faster reload of an auto pistol vice a revolver. I have an autofeeding 357mag and its not the most reliable platform.

They're close enough in the numbers that the difference is mostly academic. I like Bill St. Clair's muzzle energy calculator (http://billstclair.com/energy.html) for quick comparisons like this, and based on 357 Magnum with Remington Golden Saber at 158 grains and a muzzle velocity of 1235 fps, the "efficacy" number is 54; Remington Golden Saber in 357 Sig, with a MV of 1350 fps and 125 grain bullet, scores 51. The perfection of the calculation method can be argued all day, but at least it gives one a kind of yardstick....

I'll take the capacity advantage of any semi auto in .357sig. In it's prime popularity, the .357 magnum was the cats meow. Today, there are so many other options due to modern ammo technology.

I wasn't aware that the two rounds performed so close. I just got a 10mm because I liked the way the 357mag performed in my old revolver but wanted higher capacity (and a Glock, more importantly). Guess I didn't have to go up to that big of a round, but either way I like the 20 I have.

From what I have read the 10mm in the hotter loadings is in the 41 mag range

Yes. This is why the whole 357sig round was made in the first place. It is my choice for carry.

Modern .357 magnum can get velocity and energy well over the 125gr. at 1450 fps that the world famous "one shot stopper" cartridge was getting back in the day.

That said, Sig's goal was to mimic the 125gr. at 1450fps ballistics from a 4inch barrel. Initially they did that, now a days the factory SD ammo seems to run 1350-1375, but of course you can get buffalo bore ammo rated at 1430fps out of a 4 inch barrel or the Double Tap ammo at 1450 (although double tap's chronos as of recent apparently have shown this load to be underpowered from what is advertised).

So technically if you want this round for it's velocity you can go buffalo bore at 1430 and get close to the 1450 magnum velocity on a round for round basis.

Now there is more to what made the .357magnum in 125gr. at 1450fps it's reputation as a manstopper, such as bullet design, which is different than .357sig bullet designs, but I think the .357sig does a good job at what it does. 15 125gr. .355 caliber JHPs at 1350-1430 out of a 4 inch semi-auto (Glock) is hands down better than 6 or 7 shots out of a 4 inch revolver (Smith) IMHO.

Really, revolvers have feeding issues??

Believe it or not revolvers can and do fail. The turning mechanism on any revolver is not full proof.

My carry is a H&K P2000 357 Sig. Got turned onto that round a few years ago. Only drawbacks are price of ammo and sometimes its' availability is limited.

I didn't realize that. I'll have to stack some 2x4s together and see how much different the penetration is between a 357mag and the 10mm that I have now. There was a big difference between my 357mag and my .40S&W before which is why I thought the 10mm and 357mag would be so close.

I know shooting at layered boards isn't the best test, but it is fun and is the best gauge I have at the house.

Sounds like 357sig is a nice little round.

THe revolver round is a bit more powerful, but the Sig round duplicates a very successful loading of the revolver round.

There is a world of difference between these two rounds. 357 magnum can be loaded MUCH hotter.

I own both. The only similarity between the two rounds is the numbers 3, 5, 7.

The mag will outperform the sig with heavier loads due to more case capacity. The mag can push a 158 gr round much faster than the sig can, and that would give you much more penetration than a 125 gr.

As much as I love 10mm, it ain't no .41 Mag. Hot 10mm = mouse fart .41 Mag. That said, I want an ultralight .41 snubbie.
