Awww man, that would aggravate me!Well, my problem was that the CT red dot would not seat flush on the slide. You could see a little daylight underneath it which I’ve never experienced with any other red dot, and I have several on handguns. I took it back to my dealer, he contacted S&W, and they wanted him to send it back. That’s where I am now, new holster, 400 rounds of ball, and no pistol ! Dammitboy !
