.357 sig ammo
 

This looks similar to the 40 S&W ammo I have. Are they interchangeable? Sorry I still consider myself a gun newb. :confused_ma:

IMHO, NO!!!!!!!

Re: .357 sig ammo
 

The 40 will not chamber in 357 sig. The 357 sig will chamber and shoot in a 40...without much effect. If you own a Glock 40, you can also buy an extra barrel or two to shoot all of these. Great versatility...

Good to know. I have a 40 S&W, and just got a .357 Magnum. In my excitement of picking up ammo, I accidentally grabbed 3 boxes of .357 sig and noticed how close they seem to be to the 40 S&W. So just to make sure I am understanding you correctly, I should be able to use the .357 sig ammo in the 40 S&W without a problem or would I need to buy a special barrel for the 40 S&W to accomodate the .357 sig ammo?

You may be able to buy an extra .357 Sig barrel for your .40 S&W...what 40 do you own?

Smith and Wesson 40ve Sigma

It's 2 different calibers, .40 cal & .38 cal .....the sig .357 is made only for the sig auto, not a .357 Revolver

Re: .357 sig ammo
 

You CANNOT interchange .357sig for .40 or vice versa UNLESS you own a Glock and have a drop-in barrel for caliber conversion. Also, .357sig ammo is only for .357sig firearms NOT .357 Magnum and vice versa.

I do believe that Glock .40 mags will accept and load .357 rounds successfully but not vice versa.

I can't speak for other firearm manufactures insofar as barrel conversions, but I do know you can buy conversion barrels for Springfield XDs in only the Tactical or Service models.

Or, a Sig....duh.

Thanks for the replies guys. I'll just take the .357 back this morning and replace it with .357 magnum like I meant to do the first time. :bear_w00t:
