Hey everyone, I have 2 questions for you today. My grandfather recently passed away and after going through the house we found his old pistol. The story is that my grandfather bought a gun, brang it home, than when his wife found out about it, she made him "fill the barrel". I'm not quite sure what that means, and I'm on vacation so right now I don't have access to it for a couple more days. My questions are what does a filled barrel mean, and is there any possible way to fix it, as it's my grandfather's and would like to get it working again. Thanks.
