I have the 9 shot 4" adjustible sight bull barrel model in blue, I have put thousands of rounds through it over the last 6 years. Its my favorite .22lr revolver. I use it to teach new folks to shoot a handgun.
It has a great double action trigger and an even better single action. IMHO its the right size for a .22lr revolver, a little bigger than a J frame and a little smaller than a K frame.
The light strike issue is a matter of cleaning the cylinders, the .22lr bullet crimps over the edge of the case not inside it, so after a while the wax lube that builds up in the cylinder and the crud from firing will stop the .22lr rounds from fully seating. The hammer blow then seats the round resulting in a light strike and a fire on the second strike. This is a problem with almost all .22lr revolvers that have a chamber diameter tight enough to ensure good accuracy. The solution is to fire copper plated ammo, federal is good, and to clean the charge holes regularly with a brush.
I paid $230 OTD for mine NIB in 1999.
