Here are a few specific features that make a shotgun tactical.

18 to 20-inch barrel:

The length of the barrel is imperative as it tends to keep the weapon short and maneuverable when it is used inside buildings and vehicles as well. Eighteen inches barrel is the shortest as you can legally possibly go without pursuing a tax stamp and federal registration.

Pump or semi-auto operation:

Shotguns come in all possible flavors. Such varied flavors include semi-automatic, pump action, lever action, and bolt action, single and double barrels. Among these, the most practical for home defense is the pump and semi-automatic actions. Why? Since these two are the fastest forms of operation available for a shotgun.

A good set of sights:

Majority of shotguns come with a single bead at the end of the barrel and which acts as a sight. These are applicable for a lot of applications but if you wish to get the most of out of your shotgun, attach a front and rear sight. Consider attaching a quality red dot sight for maximum efficiency.

Sling mounts:

a sling allows you to attach the weapon to your body. This is quite practical as it will enable you to retain the weapon and to allow you to use your hands for other tasks and moreover it makes it difficult for an attacker to strip you of your attached weapon.

Chambered in 12 or 20 gauge:

When it comes to semi-automatics, there is no doubt that the 12 gauge is the most common combat shotgun caliber. The 12 gauge is regarded as the more powerful option as well. Besides, it makes the firearm larger, heavier and recoils quite fiercely. A 20 gauge round, on the other hand, is still very potent and is considered much friendlier for

The capacity of 4+1 minimum:

The shotgun avails shells which are quite large and therefore most shotguns are limited in capacity. Although 4+1 will settle most encounters, preferably using something more like the 7+1 will give you an extra edge.

A stock:

It is no question that any fighting shotgun requires a stock. Pistol grip shotguns are handy, fun and look cool on specific situations. Although, a shoulder stock makes a shotgun easier to handle and even more comfortable to shoot accurately.
