Dry Firing

One of the things I cover in my CHL class is how to dry-fire safely. I present some rules for dry firing that arose from an unfortunate incident involving a DPS officer, and show how each of those rules is designed to prevent a similar negligent discharge.

Why would we want to practice dry-firing? There are some excellent reasons for practicing with an empty handgun, but at least one drawback (covered below).

The first reason that occurs to just about everyone is that dry-firing is cheaper than live firing. That was true even before the availability and price of ammo got ridiculous a little over a year ago. But that might not be the most important reason.

Note that dry-firing a center-fire pistol manufactured in the last 100 years or so should not damage it. However, if you are the least bit concerned about that aspect of dry-firing, you can get a dummy round (the ones sold at the local gun stores are the SnapCap brand) with a semi-hard plastic insert in the place of the primer. They cost a couple of dollars each, and are sold in packs of 6. Although pricey, they can be re-used indefinitely. If you have a rim-fire gun (typically a .22), you MUST use a dummy round to prevent damage to the firing pin.

Dry-fire practice gives you the opportunity to go through some things that you just can’t reasonably do with a loaded handgun. Indeed, practicing a draw from concealment will get you kicked out of most shooting ranges. With an empty handgun, you can (relatively) safely practice things like jumping sideways or rolling on the carpet while drawing from concealment — skills that might someday come in very handy.

Dry-fire is also very good for marksmanship training. This may be counterintuitive, since the main difference is that in dry-firing, the gun doesn’t make a loud noise and try to jump out of your hand, so it isn’t ‘realistic’. The problem is that even though you should always perform the squeeze sequence so that the trigger-break is a surprise, the fact that you know that the gun is going to recoil makes it very difficult to avoid anticipating it. Dry-firing leads to a different type of “muscle memory”, where you honestly are not considering the recoil, but the follow-through. That “muscle memory” will carry over to live-fire practice (and to actual defense use), and your marksmanship will be better on that account.

You can get some of the benefit of that no-recoil “muscle memory” by getting a .22 conversion kit if there is one available for your particular handgun, and use that for at least part of your live-fire practice. While it still makes a noise, it isn’t nearly as loud, and the recoil is so slight you might not even notice it.

A potentially major drawback of dry-firing is that you don’t get quite the same trigger pull sequence as you get with live fire. For instance, with a Glock, you have to manually rack the slide every time before you get to the normal trigger pull, because the Glock is single-action-only. On a D/SA pistol, the first round can be fired double-action (the trigger-pull cocks the gun) and subsequent rounds are then fired single-action, because the recoil of the live round does the work of cocking. When dry-firing a D/SA, every trigger pull is double-action, which is typically several times the force required for single-action. I have actually experienced a case (during a DPS range test) where this slight difference in “muscle memory” caused me to drop a point on the 2nd round. After that, I knew what the problem was, and corrected it — but in a real firefight, that might be a disaster.

Still, I recommend a combination of live fire and dry fire practice. As mentioned above, a .22 conversion kit can be useful for practicing your live-fire marksmanship at a cost substantially lower than using centerfire ammo.
