New sights for mp core

[Rick frank]

I recently pick up a m&p core ported with the thought of using the stock sights for steel. I though having the option of adding a red dot was a good idea something I mite do in the future but as long as I can I rather use iron. The problem I'm having besides the front sight turning black after a few mags there is way to much light between the front and rear sight notch the rear is to big or the front post is to thin I can shoot a tight group at 10 yards but at 18 yards I'm all over . Are these sights meant for co witness only ? any suggestions on other type of sights would be good for steel Thanks

Plus one on the Dawson. I don't know how much luck you'll have with this FO staying clear with the ported barrel though.
