Being a military and law enforcement firearms instuctor of over 30+ years I will tell you that as long as you teach her safety and the basics fundamentals as far as stance, proper grip, breath control and weapon function. You will find that women are some of the best students. This because they have no bad habits, egos and listen to what they are told as far as instruction. The most of them become very good shooters due to this. The only area they lack is upper body strength so do not push the lessons out over a prolonged period of time. Getting tired and becoming frustrated as a result will be a discouragement to her. Keep taking her to the range, be patient and I think you will be amazed as to her improvement. If you do get an instructor be sure it is an instructor that is more focused on her improvement and learning fundimentals than impressing himself or her with his skill, how wonderful he or she is and knowledge! "EGO!"
I will leave you with a note concerning assisting her with her training. Safety is Number One! Basic shooting fundimentals is number two and repitition is number three! Followed by Slow is Fast and Fast is Smooth!
Above all both of you enjoy her new found interest! Share the excitement with her and have a great time! Walk slow and do not burn her out or discourage her by letting her get tired at shooting sessions~
