Browning BuckMark site adjustment

[sashmish]

Good morning all,
Yesterday I purchased brand new Buck Mark pistol with Rosewood grips and fiberoptic front site.
Shot a few rounds and needed to make some adjustments on a rear site.
According to provided manual you just turn the screws with a flat screw driver to as many clicks as you need.
However, the screws would not move at all and I did not want to force them.
Is there a trick to it that I am overlooking?
Any input will be greatly appreciated.
Best to all,
Alex.

I don't have mine in front of me as I am at work (and they frown upon that sort of thing here) but if it is for windage and and there is a screw on both sides, you will have to loosen one side before you tighten the other.

Also, make sure you use a screwdriver that is large enough to almost completely fill the slot. This will reduce the chance of slipping and/or damaging the screw.

Just to confirm, tbhupe's instructions did the trick for you?
