12
12 gauge is thicker than 20 gauge. The lower the gauge, the thicker the sheet metal or wire.
There is no difference. A 500 is a basic Mossy 500 receiver shotgun. Unless the gauge is stated, it's assumed it's a 12. The 500A is simply stating it as a "12 gauge" 500 in its name. The Mossy 500A is a 12 gauge model 500, the 500B is a 16 gauge model 500, the 500C is a 20 gauge etc. There was no 28 gauge so there is no 500D, contrary to many sources, so the next one was the .410 called the 500E. A 12 gauge model 500 and a 500A are the same gun.
These shotguns came in 20, 28, 16, And 12 gauge calibers
Yes the stock on a Winchester Model 12 16 gauge is the same as a 20 gauge. 16 gauge,20 gauge, and 28 gauge are all the same for the Winchester Model 12. Thanks, Tim
a 20 gauge is a type of many shotguns but it is smaller than a 12 gauge but bigger that a 410. a 20 gauge is a good shotgun for all ages.
It was made between 1921-1922
