S&w pro series hiviz sight installation and quality - HiViz S&W .250 Height Front Illuminated Revolver Sight

The sight that I purchased was a HiViz 0.250" height for my S&W 986 Revolver. The sight appears to be of very good design and quality. I removed the original sight and installed the new HiViz sight in no more than 5 minutes. It seemed almost too easy. And with that said, I then went to the range for a rear sight adjustment session and discovered that there was no adjustment needed. It was already shooting point of aim at 15+ yards. It has been, thus far, a great experience. I would recommend this sight especially for range sessions.
