Some considerations here and recommendations. Don't shoot 357 mags in a scandium or titanium lightweight revolver. Muzzle blast is horrendous. Bullet setback occurs quite frequently and would bind the cylinder. The bullets pull out of the cases and jam the cylinder. This disables the gun completely. Even 38 special +Ps have had this happen.Nerve damage can happen within a few rounds or if more are shot. Tingling in the wrist or arm is a sign of trouble,but why wait for that to happen? Accuracy from the TI and SC series for S&W are not as accurate as their 442,642,60,and other makes. This has been , in detail, written up in many of the police magazines and shooting journals. I am looking at Mas Ayoob and Wiley Clapps info on this while posting. I have fired two different Sc small models and can say I agree with their recommendations. Recoil was savage, painful, and even with double hearing protection outside was somewhat disorienting. Much larger and taller folks than myself were handling the guns better, but the consensus was that most were not impressed,nor would they want one. This was at an IDPA BUG gun shoot. Everyone was trying out various revolvers and pistols after the main event. Being short didn't help. S&W 442,642,60, and other models would be better choices for carry. Rugers SP101 is a good pick due to dureablility and accuracy. Taurus makes good aluminum framed snubbies as well if price is a major concern. Ported barrels do take some of the sting out,but am not sold on ports on a revolver that is close into the face or body spitting blow torch like exhaust. There may be Sc and Ti users here that are ok with shooting the small snubbies. The bigger Sc and Ti can be shot with full loads and the specials and be fine. Hve shot the bigger cousins of the snubbies,but only a cylinder or two. So take these recommendations any way you want to. Remember, one must normally practice more with a smaller revolver due to it being harder to use in a deadly encounter than a larger version. Good luck on you search.
