ETA: Lot's of folks try to buy the lightest weight J frame they can get. Don't! A .357 mag out of a super lightweight gun is a pain to shoot. I kid you not. When I shoot hot .357 loads at the range it literally feels like some one is hitting me on the wrist with a broom handle. Each time I fire it's like BANG, whack!
An all steel J frame still carries real nice but it won't break your wrist.
