The Jericho 941 R is a double action/single action semi-automatic pistol. While the R-versions of Jericho 941 feature a combined safety/decocker, which on safe also decocks the pistol, the decocker version of CZ-75 (CZ-75BD) features only a simple de-cocker. The barrel of the CZ-75 is traditionally rifled, while the Jericho 941 features a polygonal barrel, furthermore the Jericho 941 is substantially heavier. These differences translate into substantial differences in the condition in which the gun is carried, and in preference.
Tuco Salamanca uses a Jericho 941 R with a two-tone finish as his sidearm. In Grilled, Jesse takes it from him while they are fighting on the ground and uses it to wound him. It is later buried in the desert in the following episode.
