A 45 ACP round has a larger projectile (more stopping power). So why would anyone pick a 9mm? Answer: less expensive ammunition, less recoil, faster projectile (9mm can penetrate some solid objects), and with 9mm hollow point rounds it increases the stopping power by a lot. The 45 ACP has a rich history in the US Military (research the 1911 .45 ACP) and for a good reason. The military now uses the Beretta 92FS (a 9mm handgun) to better align us with NATO forces' ammunition. As to your question about Glock: they are fine handguns with a good reputation, but no handgun will please everyone. I may like a handgun for one reason, and you may hate it for that very same reason. Best advice: find a friend or a range that has one, and shoot it to see for yourself. Check out the Glock 21 (45 ACP) or the Glock 17 (9mm). Semper Fi.
