I have handcrafted this pair from CREAMY color elk antler with great "bark character" to fit the models which require the relief in the back for the "gusset" (see pic.). The later Bisleys without the "gusset" seem to have just a bit different frame contour which makes for an "iffy" fit. The grips are shown on my .44 mag New Model Super Blackhawk. They are $158 shipped. Payment by check, money order or Paypal "friends & family". You will be pleased or you may return them for a full refund.
