I suspect that if you timed yourself getting 5 hits on the chest at say, 10 or 15 ft with the mag snubbie, and then did the same with a 357 Sig (in say, the P239) you would no longer consider the snubbie to be controlable enough. I would go with the 115 gr jhp in the Sig. Even with the 3 1/2" barrel of the 6 1/2" long Sig, you will get an honest 1300+ fps. I very much doubt that you will get a 110 fr to 1300 fps in the 6 1/2" long 357 snubbie, and the 1250 fps, 125 gr jhp will be doing well to get .40 second splits (in between the hits) while the auto will get .20 second or less. Why be twice as slow as you need be? Also, the Sig lacks the cylinder bulge, holds 7 rds, reloads 2/3 times as fast, and the spare mag isn't a concealment problem (as the revolver's speedloader is) Without the speedloader, the auto reloads 4 times as fast as the revolver,and 5 rds isn't all that much, when you have no round up the spout while you reload! Given the severe tendency to screw up a revolver reload under stress, 3-4 rds had better resolve your problem. Normally it will, of course, if you can shoot and if you keep your head.
