I would think if you think a .45acp is a great self defense cartridge, the .44 spl should be able to be loaded pretty close without too much of a strain. Looking at Quickload, the .44spl is a rare round where the SAAMI pressures are higher than the CiP (euro) pressures - that is almost never the case. So it definitely hasn't been nerfed in the spec like the .38spl. Pressures near the top of a safe range in a 200gr Hornady XTP are predicted at 900fps at 356ft/lbs out of a 4" barrel. Compared to the .45acp in it's GI issue 400ft/lbs pretty reasonable. Of course if you view the penetration inadequate, then you always have the option of loading ball ammo, worked fine for the military. I don't know about you, but I think that is plenty enough recoil for a small revolver, and enough of a round to put down a bad guy.
