I like to see a full length guide rod. I don't know why, but I do. Just about every semi auto pistol today has one and I have to assume it's for some kind of a good reason. JMB made that gun the best of it's time, but that's been a while and improvements have been made since. Not saying the guide rod is an improvement, but it could be. Personally I like the wider grip safeties, but JMB didn't design those either. I have to admit that I'm not a 1911 purist and I like about every version of the 1911 I've ever seen.
