I’ve had a few questions on dry-fire, so let’s talk about that.
I am a big fan of dry firing when conducted properly. Dry firing fosters good trigger control, and especially aids the drawstroke and presentation. It also exposes problems with equipment like holsters.
In the TAG, LLC Progressive Pistolcraft course we teach good dry fire methodology. The critical issue is to ensure all live ammunition is physically separated from the room when dry firing. The line at Gunsite is to "put your ammo in a sock and place it in your empty bathroom tub".
