.357 Sig is an awesome round that can be shot just as well as any other with practice. Even double taps are manageable. I like the .357 Sig for more than just its performance out the barrel, I like the tapered cartridge, from all accounts, it lends to its reliability in the feeding process, and that is very important, as we all know. The recoil really isn't that bad.
Here's my 357 Sig (Glock 32C). 4 shots from the draw in 1.8 seconds. First two rounds are 1" apart, second two are 4" apart.
I actually shoot this pistol better than I do my Kimber.45. The penetration of either the 357Sig or the 45 are pretty much equal, but that initial impulse (wound channel) is pretty impressive for the 357Sig.
