Ruger only makes one post style front sight, which is 0.430" in height. I didn't ask about the FO sight that accompanies the V-notched pistols.

So, my plan is to get a lower post front sight, and perhaps a second lower front sight with a green fiber optic in it. Midway has a couple by Tactical Solutions that should fit the Mark IV and measure 0.365, so we'll see how it goes. It will be a couple weeks before I can make the swap and try the new sight(s).
I have a M4 22/45 and I put Williams fire sights on it. Originally I bought A TS FO for the front sight. By mistake I got the.365 when I was supposed to use the .440 size. Send me a pm if you are interested in it.
