I know that there are shortcuts on these clearance drills that lots of folks do. They include not locking the slide on a feedway stoppage and not tapping the magazine on a fail to fire. I feel like these are bad ideas. The manipulations are such that they work on any service pistol platform and in virtually any circumstance of such stoppages occurring. When you freelance them, you're asking for failure. If you're in a fight with a pistol, you're already in deep shit, and to have a stoppage is really bad. Why would you do something that might not work and that you're "customizing" for your pistol? How can you guarantee that the pistol you have in your fight is the one you planned on and not a pick up or loaner (thinking OCONUS and Commie state situations)? If you learn, practice and do the known quantity methods, you get the correct results. Finally, many (most?) folks are going to change systems once or twice during a police career and some of us change them a couple of times in a year! Witness the resurgence of the TDA Berettas here. Serious users must have something that works across the spectrum and not a customized approach. If you think that's wrong, you haven't seen somebody have a stoppage in a stress situation.
I've cleared two in stress training situations with Sims (which is notoriously unreliable), one each of a fail to fire and feedway stoppage. The fail to fire was as a bad guy with a Glock blue gun and I cleared it so quickly and shot the cop about six feet away that we were both shocked. I was admonished for not surrendering. The feedway stoppage was as a good guy on a State Department pre-deployment train up with a Beretta M9. That one got compliments from the monitors because it was done reflexively and quickly. Both were results of LOTS of perfect practice on doing something that's no fun and that I don't like to do. That's a training secret on anything physical, by the way. Do something you're not good at or don't like and do it perfectly and repetitively.
