Maximum firing range: 4,572 meters (15,000 ft; 2.841 mi)

Muzzle velocity: 1,006 meters per second (3,300 ft/s). 45 ACP round has a 230-grain bullet that travels at approximately 830 feet per second when fired from the government issue M1911A1 pistol and approximately 950 feet per second from the M1A1 Thompson submachine gun.

Twenty-millimeter ammunition is the ammo used on the M197 automatic gun. The rounds are electrically primed; chamber pressure varies from 60,500 to 61,500 psi. Projectile weight of the M56 HEI round is 1,543 grains (3.5 ounces); other 20-mm projectiles are of comparable weight. Force = MA. Mass X Acceleration. A is 3.47 times the 45. Weight is 6.7 times. So F = M X A = 3.46 X 6.7 = 23.249 times a 45. That will stop a car and put the fear of God into invaders.

Costs is a mere $13,000.

If we face societal collapse, this will discourage people fleeing the cities from entering your rural county. The Sheriff's pssee could legally own one even after Biden cracks down on guns.
