I looked into a 50 GI conversion for a 1911, and found all the same issues Hoser lists. With all the issues, there just wasn't enough reason for me to get one and I didn't want to deal with the headache. Especially since .45 is so easy to get stuff for. It's sort of like the .50 Beowulf issue, only stuff for the Beowulf is easier to get. Hence, my .458 SOCOM...
