I handled an STI in .40 this weekend. I've heard on the net that they're high quality, but to be honest, it seemed really cheap and flimsy. Price was $725 used. The mags rattled badly when in the magwell, cheap looking finish, slide/frame fit was not very good. Maybe it was a lemon? Just throwing that out there because I like 1911's and I'm a fan of .40, but that gun didn't seem very well made to me.
