Hi guys quick question for you.What are your opinions of the 9mm for defense?As you know i am a 45acp fan,not knocking anyones caliber choice here.However i find that my 1911 gets to heavy all day long.I find myself leaning toward my Glock 21 as of late big but light for it's size.And then there is the glock 17 thinner than the 21 and even lighter.I may sound foolish here but i am not sure about the 9mm,heard a lot of bad things about it.Any of em true?Why do i hear so much praise for the 45acp?Everywhere gun rags,gun stores,gun guys etc....I heard the Isreali special forces use 9mm guns.Hi Powers i think.Why don't they use the 45acp if it is so much better than the 9mm?They must see more trouble in a month in that part of the world than we see in a lifetime.Any help would be great.
