My only contact with a Ruger 1911 is the one owned by my son in law. No chance to shoot it but it seems to be a nice well made pistol.
My experience with the 1911 may not be all that much but for years I carried a Ithaca made milsurp 1911 that shot better than it looked. It was carried legally and illegally when I lived in California. Legally at the range but illegal every place else.
When I was growing up in San Francisco, I used to speed hour in F. Bob Chow's gun shop. I guess the old boy took a liking to me so I got to carefully look and handle a lot of guns.
He was a builder of custom made 1911s and rival the Pachmeyer guns very closely. Over the years he made a couple of customs for me, one like a jewel and another for carry and hard usage. The hard use gun first. The second, while not all that fancy is my picnic gun. Just simple utilitarian beauty. Both guns are very accurate with my cast bullet loads, usually the H&H #60 or a clone (SAECO #068). One load the hard use gun loves is a 200 gr. Lyman SWC, #242460 IIRC.
Another half 1911 is based on a Colt Gold Cup slide on a Caspian frame. Using a 200 gr. cast bullet load over 5.0 gr. Unique, that hybrid will do 2" and sometimes less at 50 yard when shot from a Ransome rest. All I'll add about that is the Caspian frame is rather on the rough side. Be that as it may, that gun is one hell of a shooter.
