Falkirk edged closer to promotion and the title but relied on a late goal to
claim a draw.
Darryl Duffy tapped home the opener after three minutes, taking advantage of Paul Lovering's slip.
After the break, Gow levelled from the spot after Kevin James had handled the ball. Stephen McKeown then chipped in to give the home side the lead.
James made amends in the 84th minute
when he steered the ball into the net off the post.
