My first 1911, a Springfield GI I bought brand new in 07. I saved and saved for it (two young kids, a wife that was just starting her career, and we were just moving into our own house).
I got it home, tore it apart, and promptly put "the scratch" on it. Learn something every day. I've swapped an earlier safety and some GI-style plastic onto it since. I've owned a lot of 1911s since then, but this one is a keeper to me.
