I have an sti ranger 1911. I recently purchased a set of trijicon hd night sights. After the fact I come to find out the sights are a different dimension than the dove tail. The dove tail on the slide is .300 x 60 degrees. The front sight is .335 x 65 degrees. I can't return the sight at this point. My question is, can I take off material to make it fit the slide. Ive done some fitting in the past for other 1911's. Any insight is appreciated.
