Ok, I just bought some Megar 17 round mags for my Ruger P89. They fit fine but I do not like the flat steel bottom that sticks out as it seems my pinky finger finds it when hold the pistol with the Hogue grips. I have bought some magazine base pads in the past for other pistols which worked fine. However, in this case there seems that nothing is available. The little plastic bevel pads vs. flat steel I have bought in the past seemed to solve the problem. Any links or ideas??
