Verified clear. If you received new gear, today you test it dry before you trust it. Check that the holster covers the trigger completely, holds the gun when you turn it upside down, and stays on your belt when you draw. Then run twenty draws. If you have no new gear, run the same checks on what you already carry.
Fifteen rounds at 7 yards from the rig you tested, three per string, if your range allows holster work. If the gun is new, fire fifty rounds of your carry ammunition through it before you carry it.
New duty gear has to be approved, and it has to be practiced in before it goes on shift.
A new gun does not go on your belt until you have confirmed that it runs and you have practiced with it.
A new optic or sling on the rifle means checking the zero and adjusting the sling again.
AUX (when ready): twenty draws from the new rig with no adjustments needed.
New equipment has not been tested. Test it before your safety depends on it.
You will want to carry it tomorrow. Carry it after it has earned that.
Look closely at the trigger coverage and the retention.
A holster that fails is a danger to whoever is standing next to you.
Set a break-in standard, such as two hundred draws and two hundred rounds, and keep to it.
Layer: run the draws wearing your winter coat.
Dry-fire: no ammunition in the room. Verify the firearm is clear — twice. Use a safe backstop. When you finish, say it out loud: “Dry fire is over.”
Non-negotiable. Every drill, every rep, every time. This applies to live fire and dry fire.
