Anybody have these? Are they any good? The stock sights that came on my M&P40 (not night sights) are not at all what I need on a defense pistol. The rear dots are way too big relative to the front dot. The front sight is too narrow. The rear notch too small. If somebody who has factory night sights could post a picture it'd be great. I'm thinking about getting them on my next M&P but won't if they're anything like these stock sights. Thanks.
