Hello, I'm new to this site and forum and I'm not that knowledgeable about guns so I hope you all can help me on these question, I honestly didn't know where to go. Anyway, I need some help regarding Glock 18's and some other guns for a project I'm working on, which is a comic and/or graphic novel. In the story, the Main Character uses dual Glock 18's that he modified himself to be more accurate, powerful, and shoot .22 bullets instead of .45's. Anyway I would really like some help from this forum on knowing if that is possible, and how it can be done. Is there anyone in this forum who can address these questions? I also would like to know if it is possible to shoot an arrow out of a bolt-action-rifle? And if there is, how would it be done?
