Here's a way to meet him half-way: (Although it really doesn't hurt the gun to dry fire on an empty chamber EXCEPT with a .22 rimfire) Use a snap cap. They are cheap, clearly do no harm, and add an extra layer of protection. I never dryfire without one.

(And try this....balance a penny or dime on the top of the slide, when you fire it should stay there. If it bounces 'round and slides off, a bit more practice might be indicated.)
