Fit is everything. It doesn't matter whether they are wooden or rubber, or whether the backstrap is covered. Fit to YOUR hand is what counts. I was ready to sell my 325PD until I tried Hogue finger-groove N frame RB grips. They happened to fit very well and engaged my pinky finger to aid in recoil control. Obviously, they may not fit you, but then again they might. Pachmayr Compacs were also good, but much heavier.
