So why does my carbon steel Browning Hi Power feel way more fluid between the slide and frame than both of my stainless steel .45 auto's ? This is what Ive noticed especially after they get warm from use and I have even noticed it on revolvers when they get hot from lots of shooting ! This is not to say I don't like my stainless pistols...in fact , I bought them for the more rust resistant properties over carbon steel ! Regardless , I wish they produced at least some carbon steel framed models for the few of us that would appreciate the effort , thanks !
