No offense to your sight, it looks good, but get off Bomar, they are out of business because the old man died, Mom sold a few sights for a few years out of old stock parts with a long time employee assembling. Still the best selling adjustable sight for 1911's are Bomar copies, and everybody and their brother are making them, including XS with their V notch rear. Why can you buy almost any slide already cut for the Bomar?
Good luck with your sights.
