Been a huge .22 rimfire fan since I was 10 years old and got my first .22 rifle, a Winchester Model 67A.
My first .22 Ruger handgun was and still is a Ruger Standard RST4, that my Dad needed to sign for 'cause I was too young at that time. Since then, I have accumulated personal examples of each phase that the Ruger Mark pistols have evolved into.
I've also worked with and on, Ruger Mark pistols since 1970, and have compiled quite an array of notes as to what can, and does, cause these pistol to not perform to their fullest ability.
