To help them enjoy their first experience, I start them with my LaserAim device to get trigger control and sight picture down pat without recoil and muzzle blast distracting them. Then I progress through mild .38 Spl. loads, and have them firing .357 Mags by the end of the session.
To encourage them to get their own guns, I ask what they'd do it they came home and found four big guys with knives about to rape their wife/daughter (or other evil act based on the particular person's situation).
