No. They don't always apply.
The 4 rules are very good practices to get into but it's quite silly to take pains to avoid sweeps once you've cleared a firearm. I've seen people handling firearms who've moved at weird and odd angles just to be sure they weren't sweeping themselves or others immediately after clearing...
...It's kind of amazing that no one was harmed since, according to some of you, it's so dangerous to sweep anyone with a firearm.
Tell me again how all those rules apply all the time?
...I'm in no way advocating we throw caution to the wind and start pointing guns at people whenever we like. I'm simply saying there's a safe way to handle firearms without following the four steps and sometimes, the four steps are overkill.
Please correct me if I'm mistaken, but aren't you associated with Revere's Riders firearms training organization? Is this Revere's Riders policy on firearms handling?
