Pretty much no reason for owning one outside of for collecting, as the rounds we're allowed to have don't do what the pistol was intended to do, punch through body armor, and if they can't do that, its a rather worthless round that only offers magazine capacity over a conventional pistol round like 9mm.
Could you reload the spent handgun ammunition to make it strong enough to go through armor? In Minecraft, of course. I don't know a lot about guns, but I know people save the casings and reload them.
Regarding the blood pressure discussion, it's an example of someone writing about something they don't fully understand or that wasn't explained to them very well. The latter could be an option because the officer was getting information from a grieving father. The father could have even been repeating lies Lowtax told him after blowing off an appointment or something like that.
Anyone here who considers themselves as having above average knowledge on any subject, look at how that subject is explained by reporters or other non-experts. Like if you're good at a sport like basketball, imagine how it would be reported by someone from a country where they don't play basketball so they've never seen it.
I notice anything involving medicine is very often screwed up. Even in shows that should have experts advising the writers, like medical dramas, there are things like the laboratory doesn't exist so doctors do everything with test tubes full of colorful liquids. Remember that scene in Breaking Bad, where Walt puts his IV back in his hand? You just don't do that yourself, for one thing, but I think some nurses are good enough to. And it wasn't an IV, it was a butterfly needle used to draw blood from difficult veins. The IV removes the needle from your arm.
I could go on about space as well. People are so ignorant about what goes on up there. Like they think NASA is constantly sending astronauts to the moon, like weekly, just to float around on the moon where there is no gravity and waste money. No one's been there in 53 years!
.....Well fuck me that was morbid......Everyone beat your girlfriend or wife in solitary of Lowtax tonight.
