The SLS 60 is the starting handgun for Claire and Katherine Warren in the game. As a 5-round revolver it's imperative to shoot accurately due to its slow reload time; however, with its low recoil, quick firing, and a moderate chance of headshotting zombies Claire can make use of it as an effective weapon if handled well and paired with careful mobility on the player.
It can be upgraded with the Speed Loader found in Leon's desk in the West Office, allowing all rounds to be reloaded simultaneously rather than individually.
Finally, it can be further upgraded with the Reinforced Frame to allow it to shoot High-Powered Rounds in addition to the standard Handgun Ammo makes the weapon extremely well rounded and versitle in being able to combat every enemy in the game quite easily thanks to being able to use both 9mm rounds as well as .357 magnum rounds.
It is unique compared to other handguns in the game in that moving while aiming does not reset catch/ focus at all; only doing so if a round is fired which allows for a more mobile approach in adjusting one's aim against further threats, somewhat compensating its low capacity and complements a relatively distanced engagement over close quarters ones.
