Is the Colt 1911 a fairly hard to find discontinued gun?
Colt still makes them.
Also, since the exclusive patent expired many years ago,,,
There are several (read many) companies making the 1911 pistol.
Colt, Ruger, Springfield Armory, Remington, Kimber, and many many others,,,
The quality ranges from superb to dismal.
I personally am not knowledgable enough to tell you what are the good ones,,,
But there are many 1911 aficionados here who can steer you towards quality pistols.
I'm not fond of them myself,,,
I don't want a single-action pistol,,,
I much prefer the DA/SA of my CZ-75B.
That's just my personal opinion of the gun,,,
Many thousands upon thousands of folk carry 1911's and adore them.
