I bought these, installed them, didn't like the way they made the gun feel, and took them off. Comes with everything, warrenty registration, two lens swabs, two adjustment wrenches, two batteries, cloth wrap, and box. According to the forums at crimsontrace.com, if you send in the warrenty by 3/31, you can get the free batteries for life deal. Cool concept, the dot is nice and bright, but the ergos weren't right for me. If you like houge grips on Sigs you will love these. Taking a bath at $225 shipped. Thanks!
