Pistol Calibers
What is the difference in the new .357 pistol caliber and the .40 SW as relates to muzzle velocity and energy?

The 357 SIG has somewhat higher velocity and muzzle energy. The downside is more felt recoil and usually higher ammo costs as well as fewer ammo choices. If you want a good stopping power round the 40 S&W is certainly no slouch and has been around long enough to be an established caliber. The 357 SIG has been well received, but I think its long range outlook is not yet carved in stone.

I got a chance to shoot a .357 side by side with a .40 the other day. Felt recoil and muzzle flip was more pronounced in the .357.
A cool thing about either caliber is the easy conversion from one caliber to another. Buy a Glock or a SIG in either caliber and you can get a conversion barrel for the other.

Both the 40 S&W and the 357 SIG tend to have more felt recoil than a 45 ACP. If it wasn't for the fact that you can put more cartridges in a similar size concealed gun, more folks would just go retro and stay with the bigger cartridge or use 9mm whose manageability and economy still holds its own.

Mballai - thanks for the response. As relates to going"retro", why do you throw in the 9mm? In the same league as the 45?
Thanks in advance -0 -
Actually the "modern" 9mm is more retro than the .45. If memory serves me, the cartridge was introduced in 1901. I don't consider the 9mm quite as high performance as the 357 SIG, 40 S&W or the .45 ACP but well-designed 9mm ammo doesn't have much to apologize for if your shots are well placed.
