I have one, and a USP and Sig 220 10mm. I shoot the autos more, carry the 329 more. Worked up a 270 grain hardcast load at 1000 fps and soft grips and it's manageable. I have no interest in full 44 mag in it, don't shoot them in my 44 Mountain Gun either.
Generally carried in a Hill People kit bag. If my handload doesn't work please hand me a rifle. It is a gun for a unique purpose that needs to fed carefully, but it serves that function well.
