In the day and age of battery powered, inte-err-Matrix connected, caseless electronic fired guns there's something I like about a big old revolver.
Take a Ruger Super Warhawk, give it a firing selection change to go semi-auto, and slap a personalized grip and laser sight on that mofo. Less than a grand for something that can easily serve as a primary weapon for a secondary combatant like your local face, hacker, or mage. No smartlink means not having to worry about someone detecting it's node or hacking it to turn the safety on. Street legal with the appropriate license. As long as you have enough dice to hit you don't have to worry about aimed shots or compensating burstfire recoil.
Simple, efficient, cheap, powerful.
My other fave is the Praetor. Get the version with electronic firing, mod it with gas vent 3 and a suppressor, and top mount a smartgun system. You've got a smexy stealthy little gun with 5 recoil comp that won't be running out of ammo any time soon.
