Quick Hitman Level up in GTA: San Andreas
I kinda stumbled upon this by accident, but it's been pretty foolproof so far. It's a really easy way to get to hitman level in either the shotgun or handgun.

Note: This post is not intended for people who get offended by things like this post. : )

So, I got busted by the cops after that damned Catalina got lost trying to find the car during a getaway. I was standing outside the SAPD HQ, so I entered the building. Now, unlike GTA: Vice City, they will let you walk around the station (as long as you have no weapon armed). So, I walked around, found the secret object, then I noticed that they had two sets of body armor in the building. They also had a shotgun and a handgun just lying around.

So, if you grab either of the weapons (make sure you've grabbed the armor first), the cops will start pouring out of the woodwork, shooting at you. If you just hold your position, and start wailing on them, there will never be an end to them, and you can just keep on shooting until your skill level gets really high. In the space of twenty minutes, I managed to become a shotgun master and a handgun master (which comes in really handy with the dual-wield feature).

Presumably, you can build up any weapon skill level, by getting the weapon before you enter the police station, then opening fire once you get in. (Worried mothers, please note: No, I am not recommending this in real life, as doing this would involve the quashing of another human life which is an abomination to all things decent in a human.)

Anyway, the downside to this system is that it does put you in a lot of danger, and you're more likely to leave the building on a gurney than on your feet (just like in real life).
