A S&W J-frame Snubby in .38 Special, -maybe- an Airweight, loaded with the FBI load LSWCHP+P 158 grain bullets. No safeties, no slide to rack, oh, and no 'lemon squeezer', either. Two speedloaders, tops. Deep cover means a possibility of a one-person target. J-frames applied sufficiently may also cause a temporary loss of consciousness to 'person necessary to sneak by', without damaging the mechanisms of the gun.
