Pistol

From Half-Life - Wiki on Neoseeker

The pistol is the secondary weapon of Scouts and Engineers with an extremely fast reload rate which allows players to inflict a lot of damage in a little time.

Strategy

Before getting close to enemy players it is always good to try for a few Critical Hits from a distance while you speed up to take them down with a follow up shot or two from the primary weapon (scatter/shot gun).

If/when you run out of ammo for your Scatter/Shot Gun, it is a good idea to use the pistol to finish off enemies or as a semi of sorts to do quick runs with.
