I' m looking to get some new parts put together on my " 1911" when I get it back from a buddy, extended loan for police academy. It' s an Argentinian imported Hallisto-Molina Modelo Policia Federal .45acp, and as far as I' ve looked at it, the parts seem interchangeable with older colts, but I' ve never gotten a ruler or caliper out and really checked them, anyone know if they are compatable? I' m not really looking to build it into a race gun, unless it' s possible with it, I just want it to be more accurate, a bit faster, a bit tighter....just a bit better. My biggest concern is my barrel, I had it to almost a smoothbore when I gave it to him, and he' s shot it a lot, claims it' s still on a 8" ring at 50yrds though, anyone know for sure if there are any aftermarket parts that are easily interchangeable to it?
