I have been doing a lot of 9mm research lately because I want to get a Glock 19 but don't know if I trust a 9mm for defense like a lot of others. Now here's what baffles me, the round is dumped on by a lot of people for being not a good fight stopper but then it's carried by the SAS, U.S. Military, and so many others I cant even remember. So why is the 9mm the focus of so much controversy but carried by so many Armed Forces since the Nazi Army? I'm just curious since like I said I really was thinking of getting a Glock 19 tomorrow. I'm not asking 9mm compared to any other caliber, I'm just curious about the 9mm period Wanna kill these ads? We can help!
