Back in 2008 I purchased a new S&W .40 cal compact. So far its been a GREAT ccw. I have more holsters includeing a { MIAMI CLASSIC sholder rig from galco gun leather } than any boy can use. The only thing I have always wanted to change is the front sight. In the dark at night this particular gun is invisible and impossible to aim. The owner of the gun shop I deal with agreed new glow in the dark sights plus installation gets very expensive. What we decided to do was have the factory install a new front sight. This is the new offering ( front tritium night sight ) offered on the new M&Ps. At night in a dark room this thing sticks out like a honeymood hardon.
