I don't have any pictures of either of my pistols, and I never show them off for this exact reason. People brag about their guns and then get into messed up situations just because they want someone to see that they have one.
I went to court for a traffic ticket once and a guy was in there on a manslaughter charge because he was showing off his shotgun to a friend. His friend slapped the shotgun out of his face and the gun went off and blew his other friends head off. One guy dead and another now in jail just because you wanted to show someone a gun.
