Read the manual about the breakin and shoot good quality 230gr FMJ Ammo. Also I highly recommend buying a bunch of the Wilson Combat Mags and using them.
Don't forget to use a lot of Lub. on the slide rails while shooting I like Breakfree CLP. 1911s don't like running dry.
Don't worry about a few FTFs or FTE in the first 200 rounds.
Remember to get and extra recoil spring in time it will need replacing.
Good Shooting.
