During this time period of isolation, social distancing, and quarantine, we may be finding ourselves with nothing to do. If you are in need of a training fix, using dry fire can scratch that itch. Dry fire is also a very important part of improving our firearms manipulations.
There do need to be some ground rules though. You must use a target that has an acceptable hit zone. If you do not have a aiming point, we cannot accurately measure our ability to draw and get an effective hit on the target. It also keeps us honest as to whether we actually did the dry fire correctly. In addition to a target, it is good (not mandatory, but good) to use a timer. This can be a timer that registers your shots, or it can be a par timer that you set to challenge yourself. If you need a par timer for Android see this POST.
Whenever you dry fire, make sure that there is NO AMMUNITION IN THE ROOM. Find a room with an appropriate backstop or a safe direction where nobody is likely to be on the other side of the wall. Check your firearm, and then re-check the firearm. Check the magazines and then recheck the magazines. Once you are satisfied that there is no ammo in the room, you may proceed with your dry fire.
Dry Drill 1:
The first drill is a simple draw and fire. Draw your pistol and index on a target anywhere from 3-7 yards away (or however far your home allows).
Dry drill 2:
The second drill is a transition drill. Set up 2 targets 3 or more feet apart. Draw the pistol, fire on the first target, then transition to the second target.
Dry drill 3:
The final drill is a magazine change drill. Starting with the gun with the slide locked back, sights on target, drop the magazine and perform a reload. Then get your sights back on target and dry fire.
