Great revolvers, I have a 4" 1958 Model 19, a 6" 1971 Model 19-4, (CA Highway Patrol Commemorative) and 4" Model 586-1. As for a favorite of the three, I tend to go for the 4" Model 19. I know you enjoy yours as much as I enjoy mine.
2 "BEAUTIES" you have there! I don't have a 19, but do have a 4" 586 no dash. I have some guns that are trade stock. Nothing has tempted me to get rid of the 586. Bob
