I have experimented with different style sights on different brands of guns and have noticed that I always shoot better with a 3 dot system (Trijicon, Truglo, Meprolights) on whichever gun I shoot. Its not necessarily that I prefer these but its just that I shoot better with this style. Ive also tried Sevigny Competition, FO fronts with black rear, Ameirglo colored front/black rear,etc. and I am not as accurate. Does anyone know if there is an eye/brain connection to this? Im sure there has to be some connection to sight picture, sight style and brain recognition as far as what system works best for certain people.
