/k/. Lets pretend for a second.

I am the alpha and omega. Sun and moon, the Creator. I control all things. I am giving you one opportunity. I will give you One handgun of your choice with two magazines and one in the chamber. You will be back in time on a quest of your choosing. You must tell me the handgun and the caliber of the handgun that you wishe to use, the date, and your mission. If I find it worthy, I will send you to perform your mission. Upon completion, you may chose to stay in the time you are in, or return to your own.
