Not too bright - Truglo TFX S&W/M&P Shield, .22 Full Size Models/SD9/SD40 3 Dot Green Sight

I ordered these sight for my S&W M&P .22 because the factory sights are not very good to my aging eyes. The new rear sight is okay but the front sight is not bright at all. In addition they were very hard to install. I had to do a lot of filing on the dovetail insert to get them to fit the dovetail on the frame. Even after a lot of filing they were still difficult to slide in. They are a improvement over the factory sights but not by a lot. $0 grain standard velocity 22s shot pretty much to point of aim at 10 yards. 36 grainers were 2-3 inches low.
