I own both and the 357 sig is hands down my favorite however unless you reload make sure that you can find and afford the ammo! Here in Oregon 357sig is almost impossible to find but I lucked out and bought two cases of Speer Lawman 125tmj off Gunbroker for $17 a box. It usually goes for over $30 a box. I do reload but needed the cases and also prefer to break in new guns with factory ammo.
