Smith & Wesson Model 10

In-Game Description
The Model 10 set the pattern for all modern revolvers, and will always be the most popular handgun of the 20th century. It was especially popular with American law enforcement, and dominated the market until it was replaced by high-capacity "wonder nines" in the 80s. Early Model 10s were designed to fire .38 Long Colt and only later modified for the more powerful .38 Special. These converted Model 10s fired well, but sometimes failed to extract fired cartridges in the first stroke of the ejector rod.

Before taking long shots, you can manually cock the hammer to make the trigger more sensitive. S&W cylinders rotate counter-clockwise, so if any chambers are disabled, you can minimize the effects by making sure that one disabled chamber is lined up with the uncocked hammer, and any others are to the left. To safely holster the Model 10, make sure that hammer is not cocked.

Trivia

 * If you cock the hammer and let it down while still holding the trigger during the entire procedure, you can shoot the revolver with the cylinder open while it's spinning by spamming "F".
