Glock Dry Fire Training Timer

No ammunition in the room — not in a pocket, not in a magazine on the bench, not in the next room. Verify the firearm is clear every time you pick it up, including after setting it down for thirty seconds, and use a direction that would still be safe if the check was wrong.

Almost every dry fire accident involves a live round that entered a room already verified as clear. That is the specific failure the repeated check exists to catch, which is why it is repeated rather than done once.

A striker-fired action does not reset on its own in dry fire, so each repetition needs the slide racked. That interrupts the rhythm and is the practical reason many people use a reset device or a training barrel for volume work.

Working without one is entirely viable and changes what you can practise. Draw-to-first-shot repetitions work fine; multiple-shot strings and split-time work do not, because the reset is not there.

Ten to fifteen minutes of attentive dry fire beats an hour of going through motions, and inattentive repetitions still train something — usually the sloppiness you were practising to remove.

Writing down the par time you used makes next month's session a comparison rather than a repeat. Without a recorded number there is nothing to progress against, and the practice becomes maintenance.
