I put mine on with the big flat sides facing toward me just enough in front of the slide that when you shoot the dampenders do not interfere with the forward movement of the slide. Simms has a new dampener out this year that is one piece that is made with their enhancer 2000 design. It looks like it will work alot better, and goes on just like the old style. I saw it in their new catalog I picked up yesterday at my pro shop. Hope this help. Bhunter32.
