Birdshead OM Vaquero

Apologies if this has been asked to death...the search doesn't seem to like me today.

What parts do I need to replace the grips on an OM .357 Vaquero with a Birdshead grip?

Well I guess you need a set of birdshead grips and the screw. Or are you talking about converting a plow handle grip frame to a birdshead grip frame. Is your Vaquero a large frame or a med size frame, does it say Vaquero or New Vaquero.

Since you have an original Vaquero, a large frame, all you need is a grip frame and grips.

Even on the New Vaquero mid-frame model, you only need the grip frame and grips, but the grip frame must be very slightly modified to make it fit.
