Sorry- did not take it to be a spam post- or I would have removed it (and sent you to join other spammers )
Part of that site has a humorous story of Bill Ruger and the devil, and the design of the 22 pistol.
Assembling the Ruger 22s has caused many a cussing, and has been kicked around here several times. Once you learn how, it is fairly easy. Have not used that product, but I think I understand how it works, and could save some cussing.
