This is a pair of dense American elk antler stag grips which I have handcrafted specifically to fit the pre-war N frame. They are shown on my 1935 mfg Heavy Duty. They have a very comfortable"hourglass" contour and are an excellent fit to the frame. Should you find they don't suit you, simply return them for a full refund. They will be $155 shipped to the first "I'll take them".
