Well . . . . . . . . . . . . since the majority of good 1911s are not "acceptable" to the Kennedys . . . . . . . . I'll make a few suggestions.
First, get a copy of the Kuhnausen "The Colt .45 Automatic - A Shop Manual". It presents a huge amount of information on the 1911 in a very usable way. If you can not find hard copy, . . . . carefully . . . . look for soft copy. The reason I state it that way is that there is one site that installs a virus on your system as you try to download the manual. Take a look at the 1911 forum for info on which site to avoid.
Second, a 1911 with the original grip safety is very uncomfortable for some to shoot. As such, I prefer the models with what is known as a beaver tail grip safety. You can grip the gun far higher and have better control with those.
Third, spend some time viewing the
There is an amazing amount of really good information there and all presented in less than five minutes.
FLGR (Full Length Guide Rod) is a subject for internet discussion, but not actually an issue. Pick which ever one you like.
Ambidextrous safety is an issue for some, but being Left handed and fully capable of using the "Right Handed" safety of the 1911, I think it is just another subject for people to expound on to little need.
Grip panels are another item of discussion on the internet. I prefer the Hogue 45090 because of the built in palm swell. Some love them, others hate them. Since the are only $15, don't let it be an issue.
Have fun, shoot safe.
