Yes, it seems obvious. Yes, we know many viewers will laugh it off as an FNG error, boot mistake, or derp move. Do you have too many rounds in that loaded magazine?
We also know that many of the ones scoffing the loudest have made this mistake (or will do so in the future at some point).

That’s a topic that always sparks up a debate. All things being equal, you can leave your mags loaded. That said, the frequency of loading and unloading will impact spring fatigue (if we can call it that).
What other topics do we need to address in future episodes?
