Pistol Bench Rest?

[Jammer Six]

I do exactly the opposite-- I make sure the floor of the magazine and the dust cover are in good contact with the sandbag.

If the weapon behaves differently because of that, then all that matters is that you consistently use the same method.

I use a heavy Hart pedestal rest. If you're
not planning on using just sand or lead bags, buy a pedestal rest that has some weight to it --- like a Hart, Sinclair, Caldwell, etc. Either way, you'll have to protect the sandbags from face of revolver cylinder fire with some rags. I buy "Bag of Rags" at an auto parts store --- and stuff them under my shirt, in front of my shoulder --- when I'm shooting a rifle. With a semi auto pistol...you don't have to worry about barrel pressure on a rest, for 1911 types.

At our range...we have two 3.5 foot high steel pedestal's --- with bolt holes, so we can bolt on a Ransom Rest.
