I am changing my model 94 over to receiver sight,and expect it tommorow .I removed the rear sight,and front sight blade to replace it with one I have around here thats a hair higher.The old sights were really in the dovetails snug,especially the rear one it was a pain to get out..I went to put the higher blade in,and it went in with nearly no resistance..I have had this issue with another front sight,and finally had to shim the sight with a strip of aluminum cut from a pop can..Is there a better way?.How do you all deal with this problem. ..Thanks
