The gauge system of sizing shotgun barrels is an old one. It refers to the number of round lead balls in a pound that will fit the inside of the barrel. A 12 gauge shotgun has a barrel that is the size of a round lead ball that is 1/12th of a pound. A 10 gauge, 1/10th of a pound, 16 g, 1/16th of a pound, and so one. The SMALLER the gauge, the larger the barrel. You should note that the .410 is NOT a gauge, but an actual measurement.

12 gauge the higher the gauge the thicker the item is
12 gauge is thicker than 14 gauge.
12 gauge is thicker than 20 gauge. The lower the gauge, the thicker the sheet metal or wire.
12 gauge by far
The 12-gauge is thicker.
Some are 12 gauge, some are 16 gauge. The MX16 is a 12 gauge frame; same frame size for both gauges.

The gauge of a shotgun is determined by the diameter of its bore, specifically the number of lead balls of a specific diameter that would weigh one pound. For example, a 12-gauge shotgun means that 12 lead balls with a diameter equal to the shotgun's bore would weigh one pound. To find the gauge, you can also measure the bore's diameter in inches and then refer to a gauge chart, as the number of balls that fit into a pound decreases with increasing gauge number (i.e., 12-gauge is larger than 20-gauge).
A 12 gauge metal is heavier than a 20 gauge metal. In the gauge measurement system, a lower gauge number indicates a thicker and heavier material. Specifically, 12 gauge metal is approximately 0.1046 inches thick, while 20 gauge metal is around 0.0320 inches thick, making the 12 gauge significantly heavier.
