Joey,
The Jordan troopers cover the back strap but they continue the curve and fill in the hump that is in the backstrap of revolver frames, this allows the pistol to roll ever so slightly and is the primary reason these grips work as well as they do...now they are large grips, so be sure your hand can fit them. Ive found that if the stocks are wide at the web of the hand it spreads the recoil over a larger arrea and the back strap dosent have to be covered in that case....also herrets has a design that I havent used which seems similar to the J. troopers and they are calling it their "shooting master", you might want to look at that one as well as the rest of what they make.......
$85 or so is not a lot of money for custom stocks.....especially of this quality. Blu Magnum is almost twice that expensive and they are hi-quality as well. There are others I just dont recall att. Ive tried eagle grips and didnt like the quality of the finished product, I have two sets for concealed revolver's stuck in a box of stuff i dont use anymore......fubsy.
