I am looking at a Colt 1911 in .38 Super. I no nothing about the round so educate me. How does it stack up against todays 9MM, 10MM, 357 SIG, .40 SW and . 45 ACP. Thx I have heard it is very powerful and flat shooting a'la 10 MM. I remember hearing an interview w/some gangster, Pretty Boy Floyd I think that said the .38 Super was his round of choice for knocking down G Men in one shot haha. Whats the availability and cost generally ?
