1911 parts help. Springfield Mil Spec starting point.
Completely new to upgrading parts to a 1911 so unsure what works where and with what. My pistol that I plan on upgrading a few parts for is a Springfield Armory Mil Spec 1911-A1. My question is does one 1911 part fit basically any 1911 style pistol. I noticed looking at some of the extended beavertail grip safeties that they said Series 70 or series 80 etc... Dont know the difference but since they mostly look fundamentally the same I would assume they would fit but you know what they say about assumptions. Parts I would be interested in changing first would be the trigger, grip safety, thumb safety, sights. Any information steering me in the right direction on these upgrades or any others I would benefit from or you can reccomend are greatly appreciated. Thank you in advance.
