Frame drag is when your trigger finger drags along the frame above the trigger or along the trigger guard and pushes the gun to one side or the other while you pull the trigger. Right handed shooters will see their shots pushed to the left. You may need to adjust your grip slightly to correct the problem.
The reason this is so common on the Glock is because of the lower barrel to grip height. This may help mitigate recoil but it also requires your trigger finger to point down at an unnatural angle. This is even more common among shooters with big fingers.
So after reading this, I did some dry fire and noticed that my finger was rubbing the frame. Interested, I went to the range today (after managing to find some ammo) and sure enough, my problem of pushing to the left is gone.
I own you one Sam...
