I've never had the option of carrying outside the home for self defense, so i do not know if I would want to carry a hammer shrouded J frame or a small semi-auto.
For the home, I feel much more confident of my ability with my SIG 226 than with any of my revolvers.
And my SIG has four important advantages over my revolvers:
1) Higher capacity (10 Rd. Mag. in NJ),
2) Faster reloading,
3) Tritium night sights, and, not to be underestimated
4) Pretty blue grips.
