You can support USA Shooting (the national governing body for Olympic shooting sports) and have a chance at landing one of the coolest (and hardest to find) Ruger revolvers ever made.
Ruger is auctioning a 9mm Speed Six and all the proceeds will benefit to USA Shooting. The Speed Six, Service Six (fixed, integral rear sight) and Security Six (adjustable rear sight) have long been discontinued but they were truly excellent revolvers. The 9mm chambered version of the Speed Six is particularly desirable and hard to find. The one in this auction was manufactured in 1983 and features a blued finish with a 2-3/4″ barrel, fixed sights, six-shot cylinder, and round butt frame design.
