Need help with a glove I just got....

Need help with a glove I just bought used. It's a custom modified trap that someone had made through rawlings it's an 11 3/4 " . I was wondering if there is any way I can loosen this glove up? I prefer my infield gloves to be wide from pinky to thumb This one is kinda narrow. I play softball and the the glove opening is a touch on the narrow side.Any tips or ideas are welcomed, thanks guys
