1. I wasn't referring to "yours" b/c I really don't remember from the 4 guns I shot today which one it was:
CZ 75 B Omega, FNS Longslide, GSG 1911-22 or Ruger Mark 4 Target.
2. If it was your 75, and you've already adjusted it so "it shoots dead ring from a rest," I don't need to do anything to it: thanks for speaking up!
3. When I go back and look at some of the targets, the 75 Omega might be shooting a little low, but not much, and since you have sighted it in: it could all be me.
The factory sights in my pistols lol, and the factory sighted in Your 75 . I've found on every factory pistol with non adjustable sights (meaning no screws to adjust windage and elevation) that the factory has gotten it right and my problems have been my technique. The problems I've had with non adjustable sights have either been material (glock plastic sight sliding out), or letting a counter jockey hammer in the new sights, rear was obviously off to one side. Adjusting a sight on a beavertail is rough without the right tooling, generally tapping the sight back and forth with a hammer and punch. If your shooting low, they have different sized front posts, but to really get to where you are dialing in that tight takes some skill and familiarity with the pistol. I'd want to see targets from a rest before venturing down that road, as I don't believe the front sight post is easy to change.
