I have handcrafted these American elk antler grips to fit the S&W N ROUND BUTT frame. They are shown on my M629-4. They are plump and contoured for a LARGE hand. They are an EXCELLENT fit and have a VERY COMFORTABLE hold. You will be pleased or simply return them for a full refund. They are $165 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
