I've been loving my 629, especially since I recently installed a JPoint Reflex sight! Much more accurate! I also really like the Hogue grips that come standard on that model .44 mag, however I'm always open to modifying if it means improved accuracy. I heard somewhere that the rubber Hogue grips that come standard on the 500 magnum also fit the .44 and are interchangeable. Is this true? If so, I'd like to try the 500 grips on my .44, just to see how they look and feel at the range. Any thoughts?
