This adapter gives your 410GA break open shotgun or 410GA revolver the ability to fire 9MM caliber standard velocity ammunition.  This adapter is precision machined from high quality stainless steel to the OD specifications of a 410GA cartridge.  It will easily fit into your firearms chamber and accept any 9MM Luger ammunition.  After firing simply remove the adapter and tip upside down to remove the spent 9mm shell.  A smooth bore is gently bored through the adapter for the bullet  (no rifling).  The adapter is precision CNC machined to the exact cartridge dimensions of a 410GA 2-3/4 shotgun cartridge (SAAMI specifications).   This adapter is designed to fire standard power 9mm Luger ammunition, NO +P or high power ammunition. This adapter does not work in a 45 Colt firearm.

Adapter orientation is not important and the adapter will  work in any position.
