As already mentioned, the PSR by BOG is really good, but it's not made any longer. I tried a Pig Saddle and that worked ok, but I wanted something better.
Since the PSR is no longer made, I had Ernie send me photos of his with a tape measure in the photos so I could get a better idea of the size. With these measurements, I made my own. It works really, really well. I've shot my revolver off it as well as several XP's. They all shoot great off the system.
Using the Pig Saddle, the only drawback I found was the pistol butt. With the PSR, it's sitting on a squeeze bag. The squeeze bag helps adjust your vertical height.
Here's the one I made.
