May have mis-interpreted but the tangs on my 95 Cowboy and 336 38-55 are not drilled for tang sights.IIRC, the 1895/336 Cowboy receivers/tangs differ from non-Cowboy 1895/336 receivers/tangs in that the CB/Cowboy model's receivers are not D/T'd on top (prepped) for scope mounts, and their serial numbers moved from the tang to the side of the receiver and the tangs D/T'd (perpped) for a tang sight.
