What are the chances you will actually need to defend yourself with a firearm? We all know it's better to have a gun and not need it than the other way around, but keeping a loaded gun for self-defense carries associated risks, so if you decide you need to then for heaven's sake make it an appropriate modern firearm well suited to the task. There's no reason it should ever have to be a muzzleloader. If money is a problem work a few extra shifts and get a plenty reliable <$200 9mm pistol. If you have lost your 2A rights at a young age but are now a law-abiding, then petition the courts to restore your rights. If you live someplace you can't have a gun, and are that worried about home intruders, you did buy a steel security door and windows to help keep intruders out, right? Or how about flat out moving to someplace more gun friendly and/or less dangerous. I grew up in Los Angeles and now live in North Idaho. I didn't move because the are is safer, more gun friendly and a sportsman's paradise, but those sure are wonderful side benefits. I love to shoot all kinds of firearms, especially BP revolvers and long guns, but if I carried or kept one in the home for self-protection it would be because I wanted to and not because it was the most appropriate choice of weapons. My choice would be a percussion revolver with paper cartridges carried with the hammer down on the safety notch. I could do it, but why? My 12 gauge pump shotgun I hunt with does perfect bedroom self-defense duty and I have a Taurus G2 9mm 12+1 semi auto pistol for when I'm out. Both are available for less than $200 each. If you value the lives of you and your family enough to carry and keep a loaded gun at home then make the appropriate choice.
