This seems like something that would appeal to people who overclean their firearms to the point of causing premature wear.
I do think it’s important to use your mags enough to be confident that they aren’t defective. Beyond that, train to clear malfunctions and get back in the fight. I’ve never been issued a firearm that didn’t malfunction occasionally (typically during training classes with heavy courses of fire and not as much cleaning time as probably should have happened). Maybe I’m lazy, but learning to deal with that seems more pragmatic than structuring my life around not having a malfunction ever.
^This.
I know more than a few people that do this. Trust me, I love my guns like they are children, but you simply do not need to get every single nook and cranny clean after shooting. Heck I rarely clean my guns between range sessions besides an occasional dry patch through the barrel and a basic wipe down on critical components and oil.
You also do not need to rotate your mags with any serious frequency.
Ever tried to load the last round in brand new Sig P320 mag? I am glad to see mine finally loosening up a bit.
