Situation: you're living a dangerous life because you're a badass and decided to take a trip to North Korea to gather intel for a future attack...without telling them that. While sneaking through the capital city looking around and gathering information, you hear that they have detected you. You're on the 50th floor of a 100 story hotel, with a helicopter on the roof and a car waiting for you outside. Either way you go, there is going to be security and the military is closing in! If you go to the top, there will be less resistance, but no promises that the helicopter will start. At the bottom, you'll have to fight through floors of enemy forces. Your best hope is to be stealth and get through undetected. Let's assume all pistols are suppressed and have 5 magazines. You hit a guard with a block of cement and knock him out, and take his weapon. Since this is a hypothetical, you can choose which gun he has. Which do you take, and why? EDIT: I'm all for you guys debating and such in the comments (9mm vs .45) but please keep it respectful. There's no need to call each other names to get your point across. Thanks!
