Dodgers superstar pitcher Brian Wilson's 100+ MPH right arm ain't the only gun in his arsenal anymore ... 'cause the guy just got a sweet revolver permanently inked on his non-pitching hand.
The '10 World Series champ was walking his beard out of a tattoo parlor in L.A. yesterday ... when he unholstered the freshly-inked pistol on the back of his left hand.
Wilson's already one of the most tatted up players in MLB ... but unfortunately, this one's going to get covered up by his glove while he's on the mound.
Either way, it's pretty awesome.
