I have handcrafted these HEAVY/DENSE American elk antler grips to fit the S&W K and L round butt frame. They are shown on my M66 . They are sized and contoured for an average to larger hand. They have a VERY COMFORTABLE hold. You will be pleased or simply return them for a full refund. They are $155 shipped priority mail to the first "I'll take them". Payment by check, money order, or Paypal "friends". If you are not pleased, you may return them for a full refund.
