Pistol for new job????

[Jon707]

Hey everyone iam going through my final stages of a new job with a armored truck service here in the San Francisco bay area specifically Richmond-Oakland dangerous job in these parts heres the question.I have limited choices on handguns revolvers it can be a Smith 38/357 with 4 inch barrel or a ruger gp100 in the same or colt double actions.Auto pistols are pretty flexible .40 cal and under double action.Iam thinking a Glock 31 in 357 sig i have owned one in the past and liked it i think i would feel safe with it in the past few years there has been alot of truck jackings here so i need a good gun what do think?
