Hey guys. Installed hiviz fiber optic sights a few months ago on my m&p 2.0. I have a brass drift and 3 nylon punches which I used to install them. The rear sight went in fairly easy but the front sight was a bear! I sanded off the bottom of the front sight and it installed, but very tight. Took a good bit of whacking with the brass drift. The new sights I bought are trijicon hd. Should I be able to push the front sight halfway into the dovetail this time around? Would that create enough tension in the joint to keep it in place without loctite? Now that I've installed one set (twice) I understand a bit more. Help!
