Although this is one approach, I really feel it is putting the cart ahead of the horse. I feel it would be important to first establish a relationship and as that progresses and her trust in you goes up, the subject of firearms will become a natural part of the relationship and she will want to share that experience as well. She may not like firearms at this point and she has a right to her feelings but in time, could be your best shooting buddy.....Long before she attained the status of "Girlfriend".
