Hello, I am new to xd-talk so this is my first post so bare with me. I just received my xdm 5.25 9mm yesterday and I noticed that the rear sight, only the part with serrations to fight against glare, has a very small amount of wiggle room vertically. I know is can go down if you press on it because of spring tension but it immediately snaps back to position but once in position it has a small amount of movement upward that doesn't snap back. I was wondering if anyone else's xdm 5.25 did this? Thanks!
