Howto stop m&p front sight "walking"?

[mattj]

While shipping the handgun is a hassle, if you only send the slide, you can send it by regular mail (insured, of course).

I've contacted the dealer, and will, in fact, be sending the slide to him. I trust it will be taken care of.

Thanks guys.

M&P sights are a bitch to install. I did one with a brass punch, and it was a PITA, so I got the M&P sight tool, and it's been smooth sailing ever since.

I haven't had to remove material from the M&P sights to get them to fit, just cranked them in with the sight tool. It takes some serious elbow grease and a little finesse, but I would be surprised if they moved, as tight as they are in there.
