P5C sight elevation question

[doctorhumbert]

My new Walther P5C shoots about 5inches high at 25 yards.
I've contacted Earls Repair center for replacement rear sight. It seems shorter rear sight would make it shoot better.
The existing sight on mine is #4 (7.5mm). Earl has #5 (7.2mm) and #7 (6.6mm) .
Does anyone know which sight would make it shoot 5 inches lower? 0.3mm lower (#5) or 0.9mm lower (#7)? The sight distance is about 6 inches.

My P5C has on it and came with a #5 rear sight.

For the most part I shoot 124 gr. ammo thur it and have no problems with elevation out to 25 yds.

I hope this helps you.
