Firearm Forum Question: 12 Gauge versus 20 Gauge Shotguns

Ask A Firearms Question:
I just bought a Mossberg 20-Gauge Persuader Shotgun, which shotgun is best a 12 Gauge or 20 Gauge?
Thank you John Lowney.

Here are some Mossberg Home Defense / Tactical Shotguns:


Answer:
Blog Administrator -
To determine what is the best shot shell diameter size that is best for you (most common are the 410-Gauge; 20-Gauge; and 12-Gauge) the end use drives the final decision. Shotguns are used for sport (Trap and Skeet, or Hunting), and for Home Defense. Some people elect to use a Shotgun for both purposes. To be used for both purposes they need to be full size, not shorten as you may find in a Self Defense Tactical style Shotgun.
A Shotgun may also be used for Cowboy Shooting these are generally double barrel coach style shotguns. They maybe with or without hammers. They may also be lever action shotguns.
Also note there are two other gauges: a 10-Gauge and a 16-Gauge.
The next consideration is who will use the shotgun. Children under the age of 15 and women with small frames will find the 410-Gauge quite accommodating for hunting. Adult women generally prefer the 20-Gauge for either Hunting or Tactical / Home Defense because the 20-gauge has less recoil. Adult men generally prefer the 12-gauge for all uses.
Next thing to look at is the shot shell length capacity. A shotgun chambered that can handle 3-inch shells can shoot 3-inch, 2 3/4-inch, and 2 1/2-inch shells. In other words you can go down in length but not up, i.e. a shotgun chambered for 2 3/4-inch shotgun shells cannot handle a 3-inch shell.
Capacity is the next thing to consider. Semi-auto and Pump Shotguns will hold the most rounds. Double Barrel and Over/Under Shotguns handle 2-rounds only. Single Barrel (common in 410-gauge and 20-gauge) hold one round.
Cost may be a factor as well both in ammo and firearm. Shotguns do NOT have to be expensive to work well. I have owned Stevens/Savage, Mossberg, Remington, Ithaca, Winchester, and Saiga Shotguns.
Generally 12-Gauge Shotgun Shells are less expensive than any of the others. Again brand doesn't play a really big part in standard shot size. I have used everything on the market at one time or another. 12-Gauge and sometimes 20-Gauge can be bought in bulk keeping the per unit cost down.
Some people for home defense like the Pump Shotgun, they say if an intruder hears the pump action it will frighten the Intruder/Burglar away. Personally I think that is a bunch of bunk simply because in the middle of the night you are sleeping and don't want to think about trying to pump a round into the shotgun that should all ready be loaded and ready to fire.
The most common question I get is 'What Shot Shell Size (load number) should I use for Home Defense?'
All my shotguns are loaded with #6 Shot, this works the best for Home Defense. It has lethal impact and a good spread that covers the entire doorway or window where an intruder would be coming through.

=> To answer your question, again who is going to use this Shotgun only you, or others in the house such as your wife. If others are possible users the 20-Guage probably is the better choice. But in either case both will work.
