^ Now that's elegant.
I now see why my instructor favors Clint Smith so much, himself.
I can see my malfunction drills changing, after having seen that.

adric22, please, please, please do practice that drill more than "a few" times.
As humans, we're all different, but we all need a certain number of "reps" before our brains are able to ingrain those motions - and in a stressed situation, those actions which are not ingrained will rapidly come to be known, and in the worst way possible.
Particularly for someone who does not carry a spare magazine, malfunction clearance drills - with specific mind paid to retention of the magazine - becomes of even more importance.
I haven't shot for nearly as long as you have. I'm a beginner, as everyone here knows. I've only been shooting since November. But what I have done is send some 10K+ rounds downrange, on my main HD/class/range gun alone, in that time, and I can honestly say that this devotion, at least on the square range, shows clear: just ask any of my instructors or classmates.
With that round-count as a frame of reference, I have had only one single double-feed. This occurred with dirty ammo/magazine which I had, on that same night in training, dropped in the mud and simply "rinsed-out" with a little water.
That's one hundredth of a percent: a 1:10000 failure rate.
I have about 3K rounds on my carry gun, and it has had one single stovepipe, induced by my having severely limp-wristed its action: I was already fatigued from that day's shooting, and what's more, I also had a wrist injury.
The thing is, even with such extraordinarily low failure rates, firearms are machines, and no matter how well you take care of them or feed them, they will, at some point or another, fail. Sure, the odds are slim, but once again, we don't carry to play the odds, do we? Playing it purely by statistics, it seems silly to even carry a gun....
But that's not why we carry.
We carry so that if the worst possible scenario does come to find us one day, we are more prepared than "the next guy/girl."
Knowing how to run these remediation measures on your firearm is an absolute MUST, and you absolutely MUST drill them into your brain and muscles so that they are nothing more than second nature, so that you can keep your eyes and your brain "in the fight" and your feet moving towards cover and/or tending to your daughter, when it all
does go wrong.
In my last training class, encouraged by the instructor, I'd set up so many malfunctions (using spent casings randomly distributed into my live magazines) that other students even stopped to ask why I was having so much problems with my gun.

Not only that, but I elicited a blister, a cut, and even a bruise (which lasted for two days!!!) on the heel of my support hand, from having done the "tap-rack-assess/bang" drill so many times.
By the middle of the day, the instructor was stopping the class so that I could demonstrate malfunction clearance to other students: and he'd even given me the praise of "before I could even yell at you to clear the malfunction, you'd already done so and was shooting!" I took the praise and worked even harder, putting in perhaps twice as many spent casings after that.
Not only that, but you have to realize that these malfunctions can really present themselves in rather nasty ways.
The night that I encountered my first double-feed?
Maybe the cold rain pounding on my head and hands had something to do with it, but I simply could not extract the spent casing from the breech. I'd done everything right up to that point: locked slide back, stripped out the magazine that's still feeding so as to relieve tension - but I just could not rack out that casing: the slide wouldn't even move.
My instructor came over, gently took the gun from me, and said: "Allen, you really have to get yourself a good grip, and just
RIP that casing out." In one clean stroke, he'd done it.
I was mortified.
I truly try to do my dues as a student. I watch the Magpul DVDs beginning-to-end before every class, and I train, myself, daily on drills ranging anywhere from dry-fire to movement to malfunctions. I really do try to do my dues.
Yet, that night, I'd failed.
But I learned.
And guess what? At my next class, when a fellow student pulled himself off the line and said "hey, I just can't get that casing out of there," I went over to him, and explained to him what had happened to me, and what my instructor did - and showed him the right way to do it. Grab it and rip. His was a Glock, and he's had the thing for many, many years - also with no malfunctions. He thanked me profusely: I said "you're most welcome - but do me a favor, pass-on that knowledge you know have."
I'm not the strongest guy, but I can crush a Captains of Crush #3, and the man that I helped? sure, he may be a white-collar office-worker who's nearing retirement, but he had a firm handshake, so I doubt that he was hurting there, either. So why could neither of us positively correct our double-feed malfunctions the first time around? Because we didn't know how much force we should have used - because we thought that "oh, man, if I really used that much force, I might hurt my gun!"

We didn't know any better because we hadn't ever came upon such a situation, in our practice before.
The thing is, you can never really plan for these situations. We were lucky, we had these experiences in class. But what would have happened if those situations had occurred out in the real world?
You've gotta practice, and practice a lot (oh, and yes, a snap-cap or a dummy cartridge works, but a spent casing [just be sure it matches your caliber!] tends to induce "harder" malfunctions), and even more so if you're running multiple weapons or have special needs, such as retention of the magazine, in-mind.
