I have a Ruger P-89 SS (9mm)with realibility that will rival any AK and "combat" accuracy. I mounted an Optima red dot to improve the sight picture, but, even with a variety of reloads and commercial ammo, the group size at 25 yards firing SA only is not going to shame Sig 210s any time soon! For several reasons, I would like to improve its accuracy even though the resale value of the pistol does not justify doing so. However, after searching the internet and the book shelves, I haven't found helpful information for improving accuracy in the P series pistols. Seems people buy them and, other than a trigger job or sight change, they leave them stock. Anyone have any information on improving the accuracy of this pistol or know where I can find such information? Anyone know anyone that has accurized a P series? If so, what did they do to improve the accuracy (measured by group size at 25 yards)? Thanks.
