What a surprise I experienced today when I called S & W to check on purchasing a new replacement hammer. I explained clearly to the customer service rep that i indeed had an extension connected to the spur in order to obtain better purchase area, even though I knew it was "against" warranty specs. The gentleman explained to me that considering I was honest in explaining the hammer extension, he would have one in the mail to me by next week, no charge. Darn good customer service in my mind. Thanks for the replies gentleman, Fletch
