Hey yall. Just got my M&P9 today, and love it. I have always shot 3-dot sights. I have carried a Glock 21C with factory night sights for several years on duty, and have never had a problem with them. Recently I have been interested in the XS sight, as the philosophy behind it seems to be geared more towards self defense situations. Besides fast sight and target acquisition, does the XS sight do anything better than the standard 3-dot sights? I have also heard the XS sight is not as precise or accurate at longer ranges (25yds and out). This isn't much of a concern for me, as 25yds is the max distance I train to employ a handgun. Any insight would be greatly appreciated!
