Where can you find information out about your leinad inc double barrel 410 shotgun?

It depend's on the information that you are looking for. I can tell that, because of barrel length, the ATF is not really sure if it should be classified as a sawed-off shot gun. Dont know this as fact, just heard it somewhere. I can tell you that the mechanic's of operating the machine can be tricky, and painful if not prepared for the recoil. The mechanic's are elegantly simple, but takes practice. First off, the safety is a slide bar though the trigger body, square on the right side, round on the left. To load the peice the safety must be engaged (pushed to the right). Then you will be able slide the release forward, this is the two round button's on either side of the body, the right side having a small, hooked metal plate attached to it. This allow's you to "breech" it, the same as any breech loaded long gun, i.e. push down on the barrel. Then you put the load's in. DO NOT TRY TO BE COOL AND SNAP-SWING IT CLOSED!!! The load's tend to side prtially out and CAN catch wrong, in which case you will have an uncontrolled mis-fire (not a good thing). Ok, so lift the barrel closed and there you go. Reverse the process engaging the safety, while remembering, the refered to small metal plate may sometimes not slide forward fully, so this may have to be done manually. Now the peice is fully fuctionable. Only one barrel fire's at a time. To change barrels, it must be cocked. When cocked, between the trigger body and the hammer is a small toggle that moves right and left. Right toggle fire's left barrel and vice-versa. Use BOTH hand's, I don't care how big your hand's are. Everyone that fire's mine figure out their own way to deal with no trigger guard, but that is also something to pay attention to. All that being said, I love mine, named her the Widowmaker.
