Juuuust about perfect, but…

The fit to the pistol and optic is about as perfect as it can get. Only just a very slight gap at the rear of the optic. The 509T sits just about as low as being direct milled to the slide and the factory M&P optic height sights offer a 1/5th-1/6th cowitness which is more than usable. The finish is fine; however, I wish they would do a QPQ nitride instead of the oxide coating for even more wear and corrosion resistance and eliminate the need to keep it lightly oiled. Still better than most other 509T plates on the market.
