Decided I had to put one of these on my 410 just for kicks. $23 from Midway. Looks ugly as sin with the wood forend, will have to either paint my forend black or get a synthetic one. Haven't shot it yet but will try to later this week since I have alot of 410 slugs and buckshot laying around.
Total length is about 31 inches with the stock 26 in. barrel. Big warning on the grip says to not use with a barrel shorter than 22 inches or you will be below the legal overall length.
