I think I missed a good opportunity to fire a second barrel on the turn here, for these reasons.

1) I've got plenty of outs even if he is holding a K.
2) My Q might be good so there's value to be had.
3) I might earn myself a free showdown.

No stats on villain except that he'd folded all 3 of the 19 hands he's played on the flop.
