Ruger Mark I pistol. It was the gun that made Ruger the firearms company it is today. Designed by Bill Ruger, it was made of stampings and easily machined parts (note the receiver is a mere tube with milled slots for the ejection port, rear sight and for cocking the gun). It continued in production until replaced by the Mark II. Still a popular pistol today, the gun will give you a lifetime of satisfaction and shooting pleasure.
Vigilantibus et non dormientibus jura subveniunt. Molon Labe!
