I love my 1076. Great shooter, and nothing beats the 10mm in stainless for that old-school "heavy metal" feel.
As mentioned, the FBI guns didn't have a mag disconnect (or so it's said). It's also my understanding they had the requisite "lawyer text" engraved on the slide:
Maybe that's not entirely true. Or maybe it was added to the FBI guns later sold commercially.
This is making me think I should get a letter for mine; it has the FBI grips, and the front strap checkering. Just no mag disconnect or lawyer text.
