I’ll ask the stupid question. What happens if you raise the front sight so it is lined up with the rear sight? Also at what range are you shooting?
Most guns today are designed (sights aligned) for a Correct Point of Impact at 25 yards. Because the barrel is positioned below the sights the trajectory of the bullet is rising until gravity takes over. Therefore you can expect the POI to be low at any range less than 25 yds and high after 25 yards.
Finally make sure the sights are at eye level using sight picture #3, which is all three dots in line horizontally and the front dot center on the bullseye. If none of this helps you will need a taller front sight, do not do any filing on the rear sight.
Heyas Blade, I'm sorry to hear that you're having some issues with the Q5. However, you've answered your own question, with what you'd written here.If I raise the front sight, the top of the sights do not align with the rear. I'm shooting at all ranges but when going far like 30 yards or more, I'm missing more than usual.
This is all stock on my Q5. I didn't change anything on the gun. I've noticed this on a few Q5's at a USPSA match. I was able to look at a few Q5's who let me and it was the same. I'll try to get a pic for you if i can.
Thanks for the quick reply
