Just stole this from over on VZ's website.
This is a general edification post that might help folks who are having trouble with revolver stocks.
If you look here, it's counter-intuitive but the longer wrap-around grips will make your hand sit lower on the gun and tend to result in twisting in the hand (yaw). The reason is because unlike a semi-auto, the actual grip frame of a revolver extends well
above the trigger guard, the bore axis in a revolver is quite low overall.
Grips that fill-in between the frame and trigger guard, automatically move the hand
lower on the hump, the more they fill in between the trigger guard and grip frame, the lower the hand gets.
Add in a covered backstrap and you push the gun up and forward relative to the hand (again forcing the gun to sit higher).
You can counter this by removing "fill-in" on one or both sides of the grip frame. If you go from a wrap around to a standard grip (shown here), it seems counter-intuitive, but you'll get more hand around the gun and it will sit deeper in the hand, because the backstrap is no longer pushing the gun up in your palm. If you go to the boot grips your hand will get even higher (gun even lower) on the gun, because your fingers are driving higher into the trigger-guard/grip-frame gap than with the standard grip.
You'll see from time to time, pictures of old timer guns that used basically just the upper-most portion of a grip adapter from Pachymar or Tyler along with regular stocks. This is a grip setup that will get you HIGH on the hump and low to the bore.
