I've been a 1911 .45 acp guy for 30 yrs. I love the .45 acp and always will.
My first pistol was a MK IV Series 70 Colt. It was absolutely beautiful, shot great, and that was all it took to get me hooked. I was about 22 yrs then.
However, I'm 55 yrs old now and I've painfully realized that as I've aged I am probably shooting the 9mm better.
Whether it is a 92FS, BHP, PPS, or M&P.
I seem to able to get more hits on target, more accurately, faster with these 9mm sidearms.
And most folks agree that shot placement is key.
With state of the art 9mm ammo -- HST, Gold Dot, Ranger, etc. - the 9mm is a formidable sd round.
