Altamont? Hogue? VZ (yeah, theirs are fake wood in G10, but look good)?
Love the M9A3 in FDE, but seems it'd look just a little funny with wood grips ... it's a pure work gun, so the factory stocks suit it just fine, IMO.
That said, a blued (old-style M9/92FS) looks purely awesome with shiny checkered walnut, rosewood or cocobolo grip panels, especially with the gold Beretta medallions.
