I just got my first 1911 and its tge emp4. I know it is built around the 9mm caliber and want to put some new parts on it. Does anyone know if original 1911 parts fit on it? Like the a beavertail grip, mainspring housing, and thumb safety?
You might want to check with MidwayUSA or Brownell's because Springfield modified some of the frame dimensions from the stock 1911. My suggestion would be to run a few thousand rounds through it, since it's your first 1911, and see how you like it the way it is. The stock model has pretty good components.
