The Glock 17 shoots low and left.
Front sight is (measured at the rear corners of the sight blade):
Side of gun; 0.442"; sight; 0.3935"; side of gun (0.02425" off center to the right). And it's loose, with 0.0235" of L-R play. So it's 0.00075" to 0.02425" to the right depending on how the sight ends up.
That should make the gun shoot to the left! 1.14" left at the 25 yards we were shooting at.
The rear sight is:
Side of gun; 0.1125"; rear sight; 0.0685"; side of gun. 0.022" off center to the right canceling the error of one extreme of the loose front...
The rear sight is already drifted to the right a bit.
Dry firing here and now tells me I am avoiding moving my shoulder because 100 rounds Mosin.
When I take a sight picture I notice that where my wrist wants to be and feels right is pulling the barrel left. When I pull my shoulder up where it's a little sore from the steel butt plate abuse the geometry corrects itself.
Also moving my head against the sore muscles corrects.
Something to keep note of.
