I know a couple of people with .357 Sigs but they don't shoot it much because they say it is unpleasant (their words). They equate it to a 125 gr .357 mag for recoil impulse. I have never seen once fired .357 Sig brass for sale and factory stuff is $10-15 a box higher than 40S&W. Being on a fixed income I think money first and where can I best use it and I see no need since I already have a S&W 686 with several hundred .357 mag cases and a bunch of 110-158gr bullets.
