Item measures: 6 1/2"L x 2"W x 19 1/2"H
The MOLLE compatible breaching shotgun scabbard is designed to carry a short barrel or pistol grip shotgun such as those used by law enforcement and military personnel in breaching operations.
Two MOLLE straps on each side allow for ambidextrous mounting to your entry vest, plate carrier or chest rig.
The weapon can also be slung with the padded, adjustable, and removable shoulder strap. The scabbard is padded to protect the weapon in tight spaces.

A row of elastic shell loops down the spine allows for easy access to five breaching rounds.

It holds the weapon extremely snug, it is not going to come out by accident.
This Scabbard fits 14 inch barrel and the trigger is exposed but that's how it is meant to work.
That could be a concern for some people depending on your intended use.
If your shotgun, or firearm has an 18inch barrel then this is not the scabbard you need.
If you want your gun to be fully enclosed then buy a full length case
