Just FYI - I bought a B&J Machine P500 universal sight pusher some time back. During one use on a Sig P239 rear sight, I bent the 'pin' on the pusher bolt. Had to actually take the gun to a shop to have the rear sight removed since it was in so tight - no fault to the pusher rig itself. Anyway, that was a year ago, and I couldn't find any contact information for the company to have the parts replaced (email I had bounced) - just recently found a post about same sight pusher on 1911forum, and the poster sent me contact info for B&J Machine. I emailed with a small list of parts I had broken and/or lost offering to pay for parts/shipping. Received a reply next morning offering to send replacement parts at no cost. Good company, great product and excellent customer service.
