While it might not be secret, I am a huge proponent of light use for a number of reasons. De-escalation, target confirmation, and of course as a force multiplier. I prefer to run handheld since I have used my light for more reasons than just shooting or defense. While the below information isn’t anything new, one important takeaway is practice. You need to make this part of the routine, dry fire and live. Find something that works for you (or a few holds ideally) and start working them in. Listen to Travis, he knows.
