If you are attacked by multiple armed determined assailants, and your faithful 0.00% failure rate primary weapon fails, you'll need to hit "pause" while you and your mind process that and you get your BUG out. Otherwise, the oncoming bad guys are upon you.
There is one that I know of. A watch repair man named Lance Thomas, Ayoob wrote about him some years ago and he was portrayed on Justice Files.
Also, some reasons that were mentioned include an injury to the strong arm, with the BUG on weak side. I'd get the BUG into play faster than I would the primary in that case.
If you're going to make the "before the bad guy gets on you" argument, I'd like to point out the Teuller drill, and the fact that most BGs aren't going to advertise the attack 20 feet away. By this logic, I shouldn't carry, because the BG and his buddies will be on me before I can draw.
If you're going to make fun of gamers, please understand that there is no pause in multiplayer online games.
If your not a sworn LEO, why in the f--king world would you need a back up gun on your person. I think to much X-Box not enough real life.
No offense Skribs but are you looking for advice or confirmation?
If the injury was the result of this same attack, you are already waaaay deep in the weeds. If the injury is severe enough to render your strong side useless, well, good luck and I hope you've trained hard with your weak side drills. I do practice my weak-side draw on my primary weapon, and practice shooting weak side as much as my shoulder can tolerate. Even so, with multiple determined armed attackers and my strong side disabled, the odds are poor.
From my standpoint, it makes even more sense for a non-LEO to carry a back-up since we're almost always alone in carrying.
