Ruger MKIII, fixed sights. At 10 yards I was shooting today, and noticed I wasn't hitting my little swinger target. I shot a couple magazines onto paper, and saw it was grouping decently, but 3-4 inches left. I've not noticed this being a problem before today, but my dad mostly shoots that one, and he shoots lots of rounds at 2l bottles, so combine that with bad eyes, I don't think he'd notice 
But anyway, what can I do? It's bad enough, that in order to hit a 2 inch target at 10y, I need to get a sight picture, using the three dots, as usual. But I need to line up the left dot as if it were the front sight, so the bullet goes directly to the place just above the left dot in the three dot sight, when all three dots are lined up. If it were adjustable sights, it'd be easy, but with fixed
