High Standard pistols. Best ones are the Supermatic series, either the citation, Trophy, or my favorite, the Victor. Look on the frame for the Hamden, Ct. mark. the good ones IMHO were the original ones out of the Hamden plant. Later, cheaper production took place in hartford, ct. STAY away from the Mitchell arms Stainless repos, and the "Texas" High Standards.
magazines are another touchy area. You will want to find the metal bottom magazines with the green follower. These are the originals and almost always feed unless some $&%$&^^% "fixed them". I too went through alot of .22s and finally found ones that had the grip angle of the 1911. Oh, they aint cheap, good used ones run $400-$500, with the collectables are in the $600+.
Or you could do what I am going to do and get a Ruger 22/45. I am going to get one for my daughter so she has a trainer for the 1911. Sucks that it needs $60 bucks worth of trigger work right out of the box. dont generally care for Ruger product for my use, but that will work for her. Good luck in you quest. be safe, DC
