I have a M&P 9mm and just purchased a set of front and rear HI VIZ green sights from Midway USA for 52 shipped. I put a front sight on my wifes LCR and can tell you its great. I liked it so much I bought a set for my gun. I did some research looking for a video as I am more visual. cant seem to find one. I did read that the plunger firing pin safety is under the rear sight and to be careful not to let it fly. I also read that the front is best removed from left to right with a punch and slide held in a vise. Is there any videos or help anyone can give me? I have put hammers, safety's, triggers and grip safety's on my 1911 with no problems and other GS work. I don't think this is a big problem. Thanks for any help.
