Hello guys, I am new to the forum and recently wanted to start upgrading my Springfield XD which led me to this forum. Thanks for a great forum and group of contributors. I am in the process of upgrading my sights to Trijicon HD XR yellows and bought the Lyman Accurite Sight Tool. I was able to remove the original sights with no issues at all. Followed the directions included with the sight pusher (Which is very nicely engineered.) I know there is a lot of discussion as to sight installation direction but after looking at the originals, it looks like to me that they are installed from left to right at least in regards to the front. The right end of the front sight pad is beveled in a way that looks like you start it from that end. The rear sight is proportional dimensionally and beveled the same on both ends. I have attached the pictures for your review and comment.
