So when buried alive, make sure you have a Glock. Got it.
The problem is, with any kind of decent firearm - and there are a lot of manufacturers and designs that meet that bar - a well maintained example will work basically flawlessly through the few hundred rounds (or less) that fit within the attention span and budget of most of these internet "reviewers." In order to show any kind of difference in performance the "testers" have to come up with all kinds of contrived circumstances.
My firearms have no modifications to their basic mechanisms. I practice with, maintain, and clean them regularly. They all work, Glock, S&W, Mossberg, Ruger, Winchester... But saying "Well gosh, they both work just fine." doesn't bring viewers to your channel or hits on your website.
