This is the .454 I own, its the smallest one I know of. Its only 41oz. Very easy to carry and conceal.
I also carry a .357, either on my ankle or in an x harness. Here is a picture of it.



Its 25 1/2 oz. , still hardly noticable to carry, but heavy enough to prevent flipping, so you can rapid fire accurately.

I have a conealed permit so I can hide my backup guns, but I usually open carry one too, which doesn't require a permit in Indiana. There is also no waiting period here. I think it should go back to the old days where every man open carries, it is the main reason crime rate was so low, even though there were hardly any cops and no forensic or surveillance technology. It is why the old west bank robbers are so famous, because they were so rare, not many people had the nuts to rob a bank when it was guarenteed to be a massive gun battle, now a days anyone can try to rob a bank, because at the most there is a few security guards. Same goes with house robbery and many other crimes, criminals aren't scared to do it anymore because they know most people aren't ready to shoot them. I don't rely completely on guns, I still work out and have studied some martial arts, but if I have the option I will always choose a gun first to defend myself, most criminals will back down at the sight of one. In some situations you can just shoot a round into the ground its going to send most predators running. I would only shoot someone if I really had to. EDIT- ofcourse unless someone breaks into my house, then they are getting a couple 3" triple ought buckshots in their ass with no questions asked.
