One thing no one else has mentioned. What distance are these guns supposed to hit POA at? The bullet starts out lower than the sights. The bullet has to be aimed higher than the sights to come up to the target. If it is zeroed for say 30 yards and you are shooting at 10, then it will most likely hit low at 10. It may be dead on at 30 yards. Try shooting at a longer distance and see where your POI is. Of course, the bullet is falling also so at some point, it will be low again at distance. If the guns are on at 30 yards, the error at 10 yards is still a kill shot anyway you look at it.
