Buying on line usually has an inspection period (Gun Broker, Guns America). The seller may include statements like "no returns", but they don't count. I have bought several handguns online from Gun Broker, all have met my expectations. Contacting the seller is always possible, additional photos is another avenue of reassurance. Buying an antique 19th Century firearm is sometime a crap shoot, the price is usually an indicator of condition. As I type this I am in the process of relining a 25-35 barrel that turned out to be a rusty water pipe.
