I have 2 Detective Specials. Both are the shrouded ejector rod variety. One shoots very high and to the left. The other shoots high but on center. Does anyone know of any way to correct these problems? Is this a trait of the Detective Special? I am shooting standard fmj 130 gr. factory loads at 25 feet from a sand bag rest. 158 grain round nose lead ammo dosen't change the point of impact much.
