Gonsilli, I shoot the Mdl. 41 5.5" HB. I started with this Mdl. around 1965 as I recall. I strayed for a few years shooting other fine target Mdls. A friend of mine USAF Capt. USAF Shooting Team at Hill Field AF Base Ogden, Utah offered me one of his pistols for sale. I have been shooting this will tuned pistol for some time. A friend has a 7.5" with the extendable front sight. This is a fine pistol also. I never use scopes so I can not talk on that subject. I am looking at changing the grips on the Mdl. 41. I am having a problem with the Smith stocks for some reason.
Bill Ruger used the Jap Papa Nambu pistol for the orginal design of the first Ruger .22 Auto Pistol. This pistol was not expensive to produce. They came on the market in the 1950s for around $25 bucks. This was half the cost of a Colt. Bill allowed a lot of guys a chance to shoot .22 pistols.
Ruger to this day allows many shooters a fine entry level firearm.
