Front Sight Height for G19

[RangerTrace]

I just got my G19 back from having some work done, which included Heinie sights. The front sight is .215 and the pistol is shooting 5" high at 10 yards. According to the Dawson Precision formula, I need a .300 tall front sight. Does that sound ridiculously tall?

Yes.

From the Glock website, the sight radius is given as 6.02 inches. The formula for sight change (as I determined it a while back) is

sc = (sr * ic)/36R with sc = sight change (inches)

sr = sight radius (inches)

ic = impact change (inches)

R = range (yards)

so for your situation, sc = (6.02 * 5)/(36 * 10) = 30.1/360 = 0.084 inches

meaning the rear sight must be elevated by 0.084 inches

or the front sight decreased by the same amount

to raise the point of impact 5 inches at 10 yards.

as I see it.

I haven't seen what Dawson has as a guide.

Oh - I might emphasize, that the calculation shown uses Glock's (G19) normal sight radius. If the new sights have changed the sight radius it will change the value of the needed adjustment.

That is the same number I get, using their formula.
