Best Sights Ever!
These sights are awesome! They're super quick to pick up and easy to be accurate when you need to. And you can do one handed manipulations, what more do you need!? Definitely recommend getting them. I will be putting them on all my M&Ps.
One word of caution though: TAKE YOU'RE TIME putting these on! I messed up my rear sight slightly because I didn't take my time and file it enough before pounding the crap out of it. So watch the video in the instructions link, he explains exactly how to install them without messing anything up.
