The original wooden grip cannot even fill my one hand let alone two. Thus I designed 2 competition grips, straight and curved. Both of them are large enough to achieve a comfortable two handed grip for me. These grips also features large palm rest and an aggressive texture. I printed mine with TPU but rigid materials should work, too.
Reuse the M5 grip screw came with your revolver when installing. But I highly recommend add a M5 washer with my grips.
