thanks so far. I am 30yrs old and have pretty good eye sight. I have been wondering though on that neck hold because when you get to shooting at 25, its to hard and time consuming to put your sights dead center and shoot. I mean, your kinda guessing and hoping your aiming at the x when shooting center of mass. I had never thought of a neck hold at 25 and will definately give it a try this spring. I would guess the front sight post on the aristocrat rib is a set thickness which would center up well with the neck, but if it dont, which thickness do you use to match up with the neck. I know when i used my stock match kimber last year at npsc I wasnt happy with my skinny front sight post and wide notch on my rear sight. I definately want to get that changed this year for duty match. My sheriffs revolver that i borrowed was perfect on front sight thickness, I suppose i could just measure that if I dont get replys, but yeah, curious to hear other view points on 25 yrd aiming.
