If it was almost any other gun it would not be so serious, but if someone stole my Model 19 I would have to treat it as a capital offense. I don't own a lot of guns, but the 19 is the only one to have any sort of emotional connection. Back in the days when I owned one gun for home defense, and never fired it (literally never), it was stolen in a burglary. The morning after the theft I went to the local sporting goods store and saw a shiny, nickel plated, S&W Model 19, 4 inch. I put the $307 cash on the counter and took that beauty home. For many years it was what gave me peace of mind at night, knowing I had it, and prepared to defend my family if need be. Its no longer my primary home defense gun, and is too big for concealed carry, but I take it to the range occasionally and just plain love that beautiful revolver.
If I were you I would continue to pursue this lowlife that stole it until you secure its return, one way or another.
