Hello all, new to the forums here. I have the opportunity to our base a new ruger American 45 acp, I have always loved the gun and considering buying it instead of a 1911 as a sidearm to my new m-1a. My question is that I wanted to capability to convert my 45 acp to shoot 45 super as well. I have found plenty of options for parts for 1911s (recoil spring of 25# etc), however I am having a heck of a time looking for it in the ruger American. If I can find a way to do it I will most definitely go with the american. I would love any input on this if anyone is familiar with or has done this to their american. Any and all advice is appreciated, but please don't recommend other firearms as I am decided between my two above answers. Thanks all!
