I am considering buying a Springfield 1911 in 9mm. If there happen to be any problems with the gun, do I need to use an FFL to send or receive it to SA? Secondly, what does MIM stand for? And finally, what is meant by the "break in period" for a 1911- what do you do special and what problems might you expect? Thanks- this is a great web site, and I am very happy to have discovered it.
