I dont know what for price your looking at but this would be a great choice, id leave it fully loaded at all time (That is if you have no kids in the house) so that way its always ready to just grab and shoot. You will never have to worry about a jam up in this if its already loaded. As fast as you pull the trigger its going to be blowing lead.
