Who's familiar with the .357 SIG?
I'm starting to take an interest in this round. I have a Ruger GP100 .357 Magnum and it's a beast, so I'm intrigued by the idea of this similar round in a semiauto. What I want to know is.....
1. How does it compare to the .357 Magnum as far as recoil, stopping power, etc....?
2. What's the real difference between them, other than the shape of the case?
3. What popular guns are chambered for it?
I love my XD 45 Compact. If Springfield would release the 3-inch Subcompact in .357 SIG, I would love to check it out.
Simulating .357 Sig with .40 S&W
The Federal Ammunition version of .357 Sig in 125 grain JHP is considered a "standard" in that caliber. The ballistics of this, according to the Federal website, are a muzzle velocity of 1350 fps and energy of 506 ft-lbs.
A couple of manufacturers make a lightweight version of .40 S&W defense ammo, including Corbon. The Corbon 135 grain JHP has muzzle velocity of 1325 fps and energy of 526 ft-lbs. This closely simulates the ballistics of the .357 Sig Federal offering above.
I believe that if you like .357 Sig ballistics and own a .40 S&W gun, that the most cost effective approach is to simply use the Corbon defensive ammo and ordinary .40 S&W FMJ for practice. This will avoid buying the .357 Sig barrel for $150 and expensive .357 Sig practice ammo, yet give you the same ballistic effect in defensive use.
