They come in the "Gripper" style.
They are big, but not too big in circumference, and the finger grooves allow me to obtain a high grip, with the grooves forcing my strong hand up tight.
Awesome for IPSC/USPSA, and when taking those careful shots with my very special loads (and yes, you can bend a Redhawk LOL).
Only way to know is to try.
Have them on all my Redhawks, and both of my GP's.
But that's just me; your results may vary.
