Ruger has long set the standard for reliable, affordable and accurate .22 LR handguns, beginning with the introduction of the Standard Pistol in 1949. Since then, the Standard Pistol has undergone a series of enhancements with the development of the Mark I, Mark II™ and then the Mark III™ in 2005. I broke bad yesterday and won an auction on a Ruger MK II Target pistol with a bull barrel. My 54-year old eyes don't do well with black-on-black sights... Target shooting, both inside and outside. So far, I've found Hi-Viz and Williams "Firebright" fiber optic sight sets for this pistol.
These Williams Gun Sight Ruger MK-II & MK-III Handgun Firesights also feature a click adjustment design for windage and elevation adjustment to ensure peak precision with every use. Fiber optics power these sights without any batteries, illuminating brightly with no maintenance required to run.
