Same thing I do in competition on the clock. If I've already fired a bunch, reload. If not, diagnose, at least far enough to figure out whether a tap-rack is going to improve or worsen the situation. I've seen a lot of "non-diagnostic" shooters create some pretty egregious jams by blindly going through their "procedures." I'm not a believer in that approach.
If you’re standing in the open while “diagnosing” during competition then you’re training yourself to stand in the open during a gunfight.
The time it takes to diagnose a stoppage (gee, I shot more bullets than I thought and now my gun is empty) erases any perceived time saved by releasing the slide lock and then there is no practical difference.
Diagnosing a stoppage falls into the “Orientation” phase of the OODA loop, which can be corrupted by stoppages that look alike. You look through the ejection port, see brass and the stoppage can be a doublefeed, an in-line stovepipe, or failure to feed. If you misdiagnose then you don’t clear the stoppage and you have to cycle through your OODA loop again. The danger of diagnosing a stoppage is it sucks your attention into your gun and away from your attacker.
Tap, Roll & Rack can be performed very quickly and it’s an immediate action that will solve many different types of stoppages. If Tap, Roll & Rack fails to get the pistol running or you detect the slide is out of battery while performing Tap, Roll & Rack then, if you’re not already behind cover/concealment, it’s time to get moving and not stand there diagnosing. When Tap, Roll & Rack doesn’t work it’s your cue to get moving because your next immediate action(s) is going to take more time to accomplish. A failure of Tap, Roll & Rack trains you to get moving.
The progression of non-diagnostic immediate actions is 1) Tap, Roll & Rack, 2) Combat Reload, 3) Clear Doublefeed.
Tap, Roll & Rack can sometimes turn a stovepipe into a doublefeed because the slide is trying to feed a cartridge into the chamber, and this is probably why you’ve seen other competitors “make things worse” when they encounter a stoppage. Retracting and releasing the slide to clear the stovepipe may allow the slide to engage the next cartridge underneath the one that’s partially chambered and create a doublefeed. During training most people incorrectly “insert” a stovepipe failure by trapping an empty case between the slide breechface and barrel hood then insert a loaded magazine. This does not replicate true stovepipe conditions. The correct way is to seat a loaded magazine and then “insert” the stovepipe fault. Inserting the stoppage correctly for training is more difficult and more risky when live ammunition is used.
