These are made from the heavy/dense crown of the antler.This is a VERY NICE pair of grips !!... I have handcrafted these from American elk antler to fit the S&W PRE-WAR N frame models. They are shown on my 1937 Brazilian contract .45 ACP (not included or for sale). They are an excellent fit and feel. If you have been waiting for a special pair of stag grips for your pre-war N frame, you will want to consider this pair. You will be pleased or simply return them for a full refund. They are $150 to the first "I'll take them". Payment by check, MO, or Paypal
