Hi,
I have a technical question.
I mentioned a few tiimes already, that I have a slight problem with my CZ75 pre "B".
It shoots to low.
Here fresh up on the issue:
My CZ75 is a 1986 Pre "B" sold to a security company here in germany. I bought it for 80,- Euros from my gun.. The psitol was hardly shot and only lied in the vault for several years.
What I have noticed is, that the front sight has been changed by somebody. This is visible, because a) the angle of the front sight is different to the usual and b) the paint job around the font sight has been renewed after it was changed. The rear sight was the original fixed sight.
Now at the range I noticed, that the rounds hit the target much to low. This means, I need to ain approx 30cm above the target center, to hit the center of the target halfway.
We first expected the problem to be myself, but a friend of mine, a gunsmith, tried shooting the pistol, with the same result. The distance we shot at was 25 meters.
We then noticed, that the front sight wasn`t at the original hight. It was filed down below the normal hight of 3.2mm.
Now this is really confusing, because when the fron sight is lowered and you use the original rear sight, the rounds should be coming in to high, but not to low, since the muzzle needs to be raised.
So we filed the fron sight down a bit more, to approx. 2.89mm. But that still is not enough.
So I made my ouwn new rear sight out an old adjustable LPA sight. (In oroginal the LPA was far to hight, even in the lowest setting).
Now the rounds are o.k. in hight.
But, this issue is worrying me a bit.
Is there any known technical issue, or would anybody have an idea, what the technical cause can be, that the rounds come in so low?
regards
Ken
