I have handcrafted these American elk antler grips to fit the S&W K and L round butt frame. They are shown on my M66 (not included or for sale). They are a bit plump and contoured for an average hand. They have a VERY COMFORTABLE hold. You will be pleased or simply return them for a full refund. They are $155 shipped to the first "I'll take them". Payment by check, MO or Paypal.
