.38 Snub Nose.
Level 1 revolver. The .38 Snub Nose is a standard police-issue sidearm. It is the quietest firearm, but it is also the weakest. This is the first gun you get for free, given to you by Luca Brasi during the mission "Sleeping With The Fishes." It holds 6 bullets, and then 36 bullets in reserve.
