Sheriff Walt Longmire (Robert Taylor) carries a 1911, .45ACP Colt Government Model with custom stag grips for his duty sidearm. Unlike most who choose to carry the M1911, Walt chooses to carry in Condition 2 (mag inserted, round chambered, hammer down) This isn't necessarily bad production/directing. There was a time when this was the acceptable method of carry, although now, most M1911 users do not recommend for safety reasons, instead choosing Condition 1 (Mag inserted, round chambered, hammer cocked, safety on) which is the way the pistol is designed to be carried.
Wyoming license plates have stacked numbers 1-23 on the far left that represent the 23 counties in the state. Wyoming residents can tell from what part of the state a vehicle is from, something that everyone in Wyoming knows. Great detail for directors to put 24 on the license plates of all the cars in the series as a made up county.
