i believe the above statement probably answers most of what works for you...........I chose the 1911 because of it's slimness (easier to carry IWB), bigger caliber (I know 9 mm is pretty much as effective as a 45 with good hollow points, but as I mentioned above, no hollowpoints for me), it looks good and I'm pretty accurate with it.i would not pay a whole lot of attention to what is on paper.... ballistic wise in this case You are going to have various arguments about velocity vs weight vs caliber in any caliber that will have its ballistic champions. Add to the fact that we are talking FMJ only and for me the only viable choice would be the 45.The main thing I want to know about is the ballistics of the .45 vs 9 mm. The rest is not very important, the debate will never end between capacity and stopping power etc. I need some facts, so anyone who is knowledgeable and willing to share ideas is appreciated.
On another side note, the U.S. Military along with various war stories from the past and present might shed some light on this subject. As far as i know in the vast majority of cases, the 45 is the preferred round due to its excellent actual history in combat. While the 9mm.....while effective, has not the same colorful reputation for getting the job done with FMJ as the 45 does. The 9mm advantage rests with capacity and recoil management to supplement where it is lacking compared to the 45.
I know you do not want to discuss the capacity argument and remove capacity from consideration......but level the playing field for one moment.....ask this question to yourself. Using only FMJ ammunition, would you chose a Glock 9mm that only had a capacity of 8 rounds......or would you chose that 1911 in 45 that had a capacity of 8 rounds?.......ballistics be damned in this case.....i will take the 45.....especially if it is offered in a top of the line 1911 like what you have and especially if i am already comfortable with the system and the method of carry.
Plus i am not a fan of the glock passive safety system......and would be more paranoid about it using IWB carry.
