This article is about the Smith & Wesson Model 3913 "Ladysmith". You may be looking for other similar named Smith & Wesson firearms.
The S&W 3913 "Ladysmith" was carried by Andrea until she was separated from the group in "Beside the Dying Fire". Afterwards it was used by T-Dog. According to Andrea, the gun was a gift from her and Amy's father for protection before they went on their road trip shortly before the Apocalypse began. The pistol is chambered with 9mm. The S&W Ladysmith and LadySmith are a series of handguns manufactured by Smith & Wesson starting early in the 20th century. Early models, branded Ladysmith, were .22 caliber.
Starting in the 1980s, under the slightly modified LadySmith moniker, S&W manufactured several short-barreled revolvers and semi-automatic pistols in .38 Special (S&W Model 36LS), .357 Magnum (S&W Model 60LS and S&W Model 65LS) and 9mm Parabellum (S&W Model 3913LS).

As the gun was a gift from her father shortly before the Apocalypse, Andrea didn't actually know how to use it properly at first. In "Guts" she used it to threaten Rick Grimes with the safety on and he had to explain her mistake to her later. This moment was referenced by Andrea in "Wildfire" and "Welcome to the Tombs."
In "Secrets", Andrea's weapons proficiency caused Shane Walsh to give her a better gun. As a result, Andrea abandoned use of the gun afterwards.
The only person Andrea is known to have killed with this gun is the zombified Amy in "Wildfire". In Season 2, when Andrea kills walkers, its with the gun that Shane gave her, including during the barn massacre scene.
