I have recently been in the market for a new handgun. Actually, I would like to start collecting and shooting modern arms. We are really into the Sigs, and H&K's. I would like to find some info that could help me know which caliber will be more accurate, etc. To tell you the truth, I am somewhat ignorant of the calibers, and the differences in them. I would really appreciate it, if someone could direct me to a website or somewhere where I can learn more about handgun ballistics, etc. Maybe even some pistol reviews. You know, the tech type thing? Thanks.
