Shooting low.

I just bought an H&K compact. After test firing it at the range it shoots very low, [groups ok] but 6 to 8 inches low.

Whats the cure?

Heavier bullets commonly will shoot to a somewhat higher point of impact.

Judicious filing of the front sight will cause you to raise the muzzle a bit when you shoot, which could solve the problem. Don't go overboard; file, shoot; file, shoot..."Oops, too much!" is expensive.

Sight radius in decimals times elevation error divided by distance to target in inches = the amount of change needed in sight height.

EXAMPLE
Sight radius 5 3/4" = 5.75
Elevation error 6 or 8" low so make it 7"
Distance to target 25' = 300"

(5.75*7)/300 = .134 sight change. Raise the back sight by half that and lower the front by the other half.

Oh, yeah, do the math with your sight radius and distance to target.

Change ammo first, if that doesn't do it try a call to it's mommie. Then if they won't do anything bout it, trim sight as above.

CAREFULLY
