Hello great people. I was wanting to change the front sight on this Ruger Mark IV 22/45 . I'm not sure how to take it off. Does it take a special tool? It looks like the hole is round. Thank to all of you in advance. All of you are great people.Paul S.

Hi, the Ruger mark IV just requires you to remove a screw. Some of the older models used a flat head screw, the newer models use a hex screw you need 5/64 Allen wrench to remove it. The screw is located right behind the front site post. It may be a little difficult to remove cause most manufacturer use thread locker for these types of screws. I'd recommend heating it up with a blow dryer, or just shoot a couple magazine threw the pistol and then try to remove the screw. Or you can try a penetrating lube Like pb blaster that should help loosen the screw. If for some reason the screws just to stuck to get I'd take it to a gun Smith before accidentally stripping the screw but you should be fine. Hope this helps.
