I own 1911's form RIA and a few manufacturers. I will say that If you plan on owning a 1911 or 1911 style pistol, you have to get very familiar with the parts and mechanics because the parts and springs will eventually go out. Extractors fitted, tuned and replaced, Recoil and FP springs are the most common. If not, it can get expensive or time costly sourcing out gunsmiths or sending it to CS later down the line. There is no such thing as a drop in part for a 1911.
