The best m&p backplate there is - trust me bro - Ed Brown Products Serrated Slide Backplate for M&P

So I’ve tried 6 backplates for M&P: NDZ, Rook, Hyve Technologies, OEM, OEM rubberized, and this one. IMO hands down the best one is this Ed Brown Serrated. The Rook is nice because it’s flat if you like that look, just metal and flat, same with NDZ, but their spacing is a little tighter on Rook. Plus you can have different images on them if you wanted. Personally, I like my backplates serrated because I don’t want anything shining off the backplate, potentially causing a glare to be in my face. The Rubberized OEM backplate coming from the original M&P 2.0 full-size releases with the OG hinged trigger is well, decent, and you can stipple it to match whatever stipple you might have on the frame itself, which is a nice bonus; however, it too can cause minute glares on very sunny days, which is why I just prefer a serrated backplate all day. HIGHLY recommend the Ed Brown serrated even over my beloved tried-and-true Hyve Technologies backplate, which has a great little Hyve logo on it but still doesn’t compete to the serrated backplate.
