If .40 S&Ws can push a 135gr bullet to 1420 fps, PLUS a 165 gr @ 1240fps, plus a 180gr @ 1150fps, all the way up to a 200 gr @ 1100fps, why does anyone need the .357 sig?
The 125 grain .357 SIG is a smaller bullet and it only has 100fps higher velocity than the larger 135 gr .40S&W. If you up the weight of the .357 SIG to 147 grains, it only makes 1296fps, compared to a heavier 165gr .40S&W at 1240.
On top of that, Double Tap loads a 125 grain .40S&W load at 1445fps, lagging behind the .357 SIG round by only 5 fps.
I don't see the need to hang on to the .357 SIG round when it is already scarce on store shelves and is more difficult to reload and re-use brass, being a necked down cartridge.
Someone defend it and prove me wrong
