Are my expectations too high?

Yeah, your expectations are too high. They all get the drop in parts and really that is why there is a cottage industry built on the 1911 and dozens of parts manufacturers in business making only 1911 parts that need to be fitted and the tools to do the fitting. Not to mention about 5,000 gunsmiths of varying skill levels who have hung out a shingle to do those same things. I mean you can't expect a company that uses plastic for the hammer spring housing to pay someone $50 an hour to fit the grip safety. Hell, I would bet they don't even pay someone to actually file the grip safety lever to fit the trigger bow. They just make the parts, or more likely spec the parts from other manufacturers, to work without hand fitting 99% of the time.

I played with a lot of the early Para guns and they weren't any great masterpieces of hand fitting and I haven't seen a single gun manufacturer in history say, "You know, we don't spend enough money on hand fitting our guns, we need to stop churning them out and really spend more time on making them perfect". Sure there are companies that do that from the start, but none that ever start as mass producers and decide to hand fit their guns.
