I've never kept spare parts for my guns, other than when I keep original parts when I add upgrades, or when I get two of something when I only needed the one.
Now I'm going to make an effort to determine what I need for each of my most important guns and get some stuff ordered. Springs seems like the most likely start, along with maybe firing pins, magazine catches, ejectors, maybe assorted pins.
I have some redundancy with most of my calibers, but it seems to make sense to have a spare parts inventory, especially for those parts that aren't overly expensive.
