New owner of M&P 2.0s, NTS Shield 9 and a 2.0 9c 4". Have new Ameriglo sights on the way so thought I would replace the factory striker blocks with the Apex. Will this get rid of some of the take up grit. Thought while I had the sights off, might as well replace. Don't really want to do more until I have more rounds through both guns.
