I have a 4 inch 44 mag Redhawk and was thinking about getting some XS sights. I called them today and they told me the front sight on this gun is like the GP100 in that to remove it you push in the release ,located above the muzzle, and pop the sight out. My gun has a front sight that is held in with a roll pin just like the SP101. The guy at XS told me that he has never seen this and told me to send him pictures. I got this gun new in box. Anyone else have a Redhawk like this?
