I would agree with the sights (tritiums!) and plunger tube. The extractor is the most chronically finicky part of the 1911 system and so that is understandable, too. All the rest of it (especially anything having to do with throating, polishing or relieving) IMHO and that of my gunsmith is pretty superfluous in new 1911's. Those were upgrades of the 1960's and 70's. Manufacturers figured out what was going on and built the "upgrades" into factory stock to make them even more attractive for initial purchase. I mean they make sense if you're buying an older or used model.Originally Posted by QKShooter
Magazines are always critical. IMHO Wilson is the best for a 1911.
I wouldn't replace factory new springs until they wear out and then go with WOLFF all around. Exception: Your gun is set up for target loads and you want to go to combat loads or especially the reverse calling for a dramatically different spring power. Buying a used gun it only makes sense to replace all springs.
I would never take a 1911 and start monkeying with fitting "rails." That's how those raceguns started messing up in matches and it would, IMHO, maybe get you killed on the street. Not me, not ever, on a carry piece.
I think full length guiderods are useless on a carry gun too. The exception being a HAARTS recoil reducer. I've used it in a Glock M21 45ACP and it does indeed reduce felt recoil and muzzle jump by at least 50%
