Nope, not in any of my Knights. Ive had Elites as early as 3 digit and 4 digit serial numbers. An Extreme and 2 "target" triggers, one came in my GMB54-120. Another cheaper one in my DISC original 45.

All were silver in color. Maybe its was some kind of SG special order batch. They sold a 45cal Wolverine with a light contour barrel i never saw anywhere else too.
