The 125 grain .357 Sig round goes about 1425 fps on average from buffalo bore: http://www.midwayusa.com/product/187...free-box-of-20

The 124 grain 9mm +P from doubletap goes about 1300 fps, and the 115 grain goes about 1410 fps.

Does the .357 SIG's 1 more grain and 125 more fps really make that big a difference over the 9mm +p? And in the case of the 115 grain, does the .357's 10 more grains and 15 more fps make a difference?

I've been thinking about getting a .357 SIG, but after this finding I might just go with a heavy duty 9mm like an all steel SIG226, shoot regular 9mm for practice and the hot loaded stuff for SD.

What do yall think?

I know I'm comparing a hot loaded 9mm to a standard .357 SIG, but the point still stands, I think.
