If you dont practice your malfunction drills with some level of realism, how are you going to deal with them when they happen when you need them? If you think they arent ever going to happen at some point, youre deluding yourself.
This isnt about being tactical or cool, its about knowing the gun youre using and to the point of not having to think about working it in a time of need. The skills translate to most of the other guns of the same type too, so its not wasted time or effort, regardless of when it happens and with what.
You dont "have" to do it every time, with everything youre shooting, but why waste the opportunity to stay sharp if and when it presents itself? Especially if you dont get to do it often.
Ive had a few squibs while shooting "quickly", all of them with revolvers, and I have yet to send another round behind it. Knock on wood. Even while moving and shooting quickly, I knew something wasnt right as soon as I pulled the trigger, and knew enough to stop. If youre accustomed to shooting while multitasking, and are paying attention, even if its only in the background, you still know when something isnt right, and its pretty obvious, and you do have the luxury of stopping and checking. And I do that if I feel the need, just after Ive done the clearance drill.
If youre shooting a new gun and having the same repetitive failures, of course, you try and figure out whats going on. If that's whats happening, something isnt right. You should always shoot a new gun until you're comfortable with it running OK. You also have to be realistic about things too, and understand that NOTHING is perfect, for whatever reason, and you need to be prepared to deal with it, if it should stop. You dont get there, if you dont practice that.
If the gun is reasonably well made and youve basically proved it in shooting it in practice, youre likely not going to have any problems with it. Most guns with good ammo are usually pretty/very reliable. Same goes for a duplicate gun you might carry that isnt shot all the time.
Even when I shoot ammo that I know is likely to have a higher rate of failures, the failures are still a much smaller number than all the other "flawless" rounds fired in between. The failures are usually sporadic and unexpected when they happen, and that's the "plus". I learn something from both of them every time I shoot too.
Look, if you think a high round count with no failures is good, great. I dont think youre being realistic in believing that really means anything, but if it makes you happy, youre good. All Im saying is, that those few that give you trouble, especially in a time of need, need ALL of your attention when they do, and if youre not well versed and comfortable in dealing with it, stopping and staring at the gun, isnt a good thing.
