I've read and posted a few threads on the 5943. I have one and I like it (after I got used to it not being a SA/DA revolver).
The frame is aluminum so it doesn't soak up recoil like a steel frame, but I shoot light loads thru it anyway. Heavier loads are not uncomfortable, just more muzzle flip. I think it would be at least as hefty as a polymer frame. It seems to be very reliable. I haven't had a hiccup with it yet. I prefer the DAO because all of my trigger pulls are the same, 1st, 2nd and last shot.
