Grand Theft Auto: San Andreas/Weapons

All weapons aim better when CJ is crouched so most of your time fighting will be in the crouch position. This also allows CJ to do combat rolls in and out of cover, allowing time to reload.

By far the best weapons in the game are the Chainsaw, the SMG and the AK-47. All other weapons are likely to only be used in passing and when available. The chainsaw is devastating because it "locks" characters in place and does so much damage that apart from special characters it is a one hit kill. It also requires no ammo.

The SMG is versatile as it can be used in drive-bys while when crouched it's range and accuracy is comparable to the assault rifles.

The AK-47 and the M4 are very similar apart from their ammo clip sizes but the AK-47 is more readily available and therefore you are more likely to make Hitman with it.

These are the only three weapons you need to carry out most of the missions and the Turf Wars.

Stealth Weapons
The two stealth weapons are the knife and the silenced pistol. In a couple of missions these are the only weapons you have access to.

The knife is a ordinary melee weapon but has a special attack mode. If you target an unaware opponent (for example approaching them from behind) and attack you should slit the target's throat killing them instantly.

The silenced pistol is the same as a normal pistol except that when fired it seems to not increase the Wanted Level as rapidly as other weapons. In stealth missions the silenced pistol allows silent kills at a distance but it is important to use a head shot kill as otherwise the target can shoot back and set the alert level in the mission.
