While a 3" M-58 would make a good carry gun, keep in mind that an N-frame snubby is a bit heavy compared to some ther viable options. A good holster would be a must.
IF I decided to go for it I'd bob the hammer too. Ahrends or Craig Spegal grips would be ordered while the gunsmith is doing his work. A call to Milt Sparks would also begin the 10 month wait for one of their excellent holsters.
