Overall these sights are a good design, my complaint is the tritium age - AmeriGlo Smith Wesson Pro Glo Front, MP Models

This is a really good sight set in terms of function. The front sight is really easy to pick up during any lighting conditions I've tried these in. Some people prefer three dot sights, but I find this style to be better. Rear sight is also designed to allow for one handed slide manipulation, which is a nice thing to have even though it normally doesn't come into play.

The sights fit the dovetails in the slide pretty well, though the front was a bit on the tight side (not an uncommon thing due to tolerances). Installed using MGW tool specific to M&P handguns.

This sight set includes a front sight with a Tritium insert for low light visibility. These are marked with the year of production and the one I received is from 2015. Without knowing the month of production, the sight could have been a year and a couple months old, or it could be over two years old. Two years is a lot of the usable life of Tritium sights for my use. So in the end, I don't exactly get full value for the money. Ameriglo says it's not their problem, so I don't know if I'll buy this brand again simply because I prefer more recently manufactured Tritium sights when buying them new.
