Was alcohol involved? Every gun shop I ever visited the clerks all were armed.

I think the idea of robbing a gun store is just not advisable altogether, but robbing it with a bat seems especially optimistic.

Maybe he thought he could use the element of surprise, i.e. the gun store workers would be so shocked by his robbing them with a bat, he could escape before they got over their shock.
