Most Colt collectors want guns in "Original" condition. Preferably unfired. Fortunately, I'm not a collector nor even a fan of Colt, so none of that matters. I've worked on many Colt SAs that weren't quite right from the factory. Seems like the "Collectors" don't really care if the gun works OK. Or even works at all. If it's a Colt, it must be Swell.
