I have handcrafted these from elk antler. They are sized and contoured for a SECURE and VERY COMFORTABLE hold in an average to large hand. They are precisely fitted to my Python. They have genuine Colt medallions. If you have been waiting for a special pair of service style grips for your Python, you will want to consider this pair. They are $168 shipped to the first "I'll take them". Payment by check, money order or Paypal "friends & family". You will be pleased or you may return them for a full refund.
