I have a lot of J-frames, and I love them all. But if I were to pick a favorite, it would be my no-dash 640. IMHO, it's the best concealed carry firearm ever produced.
I love everything about my 60-4.
I may be winning an auction for a 63-3 tomorrow with a 4" barrel, so I guess we will see if the 60-4 still reigns in my collection
642 gets my vote for concealed carry, but the humpbacks are also a great pocket carry. I'm always amazed at the accuracy of these little buggers. Long live the J Frame!
