Terry mentioned the H&R Ultra Sportsman. I have had a Model 777 for many years. This is an extraordinary revolver, single short action, and short cylinder the length of a .22LR cartridge. The bullet does not have to jump the length of a .38 Special to get into the barrel, as on a K22. Not many were made. I also have a K22 that I bought used around 1950, do not know exactly which model, but I used to shoot in the mid 90s timed and rapid double action on the old National Capital indoor range in DC. Remarkably smooth trigger. I am also fond of a Walther PPK with dural frame although of course I cannot hit nearly as well with it as with the revolvers.
