We had a variety of guns for CCW students to use. Actually I wish more students would shoot a variety before making a purchase.
Many times a student showed up with a new gun bought because an 'agency' used, seen in magazine, their buds had one, or ( my favorite) in such and such movie.
The ladies used more common sense, but still husband/boyfriend/daddy said "this is what you need".
So we would familarize with various platforms, let them shoot and make an informed choice for themselves as far as GUN FIT, platform, caliber. . They were better prepared to make an informed purchase.
We spent time with all this, including dominant eye, grip...etc,so when the qualification shooting began the students were comfortable and had fun. Many times they wanted to stay afterwards and shoot some more. Safety was always stressed so after seeing them shoot and comfortable with a student we allowed access to private range. Still the ladies practiced more.
They also tried various holsters from our collection. So when they left, they were better informed to make a purchase for CCW. Gun, holster and ammo.
