I want to put some tritium night sights on my XD, but have heard the stock sights are on pretty tight. In your opinion, should I get the sight pusher and blocks and do it myself? Should I take it to a local gunsmith? Im fairly mechanically minded as I’ve worked on cars and done maintenance for a long time now. What are the chances mess up slide/ dovetail? I will probably end up doing this with my XDe also I believe, if that affects the cost v. benefit ratio.
