I have handcrafted these American elk stag grips to fit the PRE-WAR N frame models ONLY. They are shown on my 1937 .45 acp Brazilian contract model. They will NOT be the best fit on the post war or later N frames (they will be a little LONG over the bottom of the butt). They have a COMFORTABLE contoured shape for a VERY comfortable hold in an average to larger hand. If you shoot your 1917 or similar with service style grips....you will LOVE how these feel. You will be pleased or simply return them for a full refund. ...They are $125 shipped to the first "I'll take them"
