Probably weak tight, but i'd fold it.
1) There are no draws he could be betting
2) Say there was a draw on the board, most wouldn't bet it into a pfr, who's raise will drive out 2, hurting his implied odds.
3) You still have 2 left to act and a Q is about the worst card for you when you've been cold called.
5) The pot isn't too big. You're getting about 4:1 to see a showdown and have little chance of improving.
I suppose there's a slight chance he's betting something like A and a paired X or a mid PP, in which case your raise is necessary to drive out OC's behind you.
