RE: Pin Gap
Yeah, it just takes some practice. You could consider an adjustable single pin sight but that might be more than you want to get involved with. They are really nice because you can change the yardage of the pin. The downside is that if you have a target that's at 40 yards and walking to you then you don't really know what yardage it will stop and present the shot.By the time the opportunity presents itself you may only have a split second to adjust the rest and take the shot.
