6904 but with a steel frame. Melonite finish or similar on both slide and frame. Spur hammer. Novak sights. Tritium front. Black rear. Checkered front strap. Standard plastic grips. Match barrel. Top of slide serrated. Front cocking serrations. Round trigger guard. Decocker only, slide mounted.

That'd be my ideal 6904.

And a 3913 in the same configuration.
