Let me tell you what happened to me. I had given up hope to ever finding a Knoxx recoil reducing model for my 20, so I bought an ATI stock. It was a good stock, but just not what I wanted. This past December 2012, I went to Blackhawk's website and believe it or not, they had the recoil reducing model for the 870 20 ga in the clearance section. I ordered it immediately not really thinking one would show up. I think I paid $69.99. Three days later it showed up. I think it was the only one they had. Sometimes it pays to be lucky.
