Carry the Ingram. Keep the Alpha secured in a secret compartment in your vehicle of choice. Just in case.
I agree with this. To be honest it depends on mission load out, my Gun Adept has a Yamaha Raiden that she uses when going into missions that we know the shit is going to hit the fan, but the majority of the time she carries a Ares Predator because it is concealable and keeps a hand free for other things. If you are married to using automatics I go with the Ingram for its can be concealed inside the lining of a trench coat and with specialized smart fabrics be hard to spot. But if you really want to conceal something, consider the ares Executioner that can be fitted inside of a suitcase for only 500 nuyen. However it is 14F so remember that when Knight Errant is shaking you down at those security check points.
