Any of these drills can be modified for the better by having a shooting partner load your magazine with an unknown number of rounds.
You shoot a Mozambique bang, bang, bang, slide lock - reload - bang, bang, bang...now we're training!

For the “tap, rack, bang” this writer refers to, my agency had a particularly good drill. We were handed magazines the instructor loaded randomly with live rounds and inert rounds. We were expected to shoot through the whole magazine, using the clearing and reloading drills. About 5 to 10 reps of that and “tap, rack, bang” was automatic. And it works. I’ve seen officers who haven’t qualified in a year experience a malfunction, and automatically execute the drill. Repetition is key.
