Thread: Dumb question.........

.357 Magnum rounds are straight wall cases, and .357Sig are bottlenecked cartridges for semiautomatic handguns. They are NOT interchangeable.
You want the .357 Magnum rounds (or .38 Special for a less stout round that you can use in the same pistol)

A few things....

.357 Magnum:
-exaggerated rim "revolver-style" casing
-extended 38 special casing
-been around for decades
http://en.wikipedia.org/wiki/357_Mag

.357 Sig:
-"semi-auto-style" casing
-essentially a bottlenecked 40S&W casing (although not 100% exact!!!)
-relatively new case design

Don't worry, 357 Sig isn't going to fit in a 357 mag revolver.

Thanks for the info guys! The only worry that I would have would be in buying the wrong round! My local Wal-Mart has only one box of each. I was pretty sure that I needed the magnum round, but didn't know if the other would work or not.

and it's important you buy the right ones the first time as most places do not allow for return on ammunition, so you'd be stuck with a $30 paperweight. Good luck!

Understood.

I was just drawing parallels to potentially catastrophic situations like trying to shoot 357 mag in a 38 special, 40S&W in a 10mm, or 45 super in a 45 auto. At least in this case it's not possible.

And always remember - There are no stupid questions.......

Yes sir, thanks for your reply! I need all of the help that I can get!
