Let's assume a specific bullet, such as the Golden Saber 230 grain 45 ACP (or any quality ammo).
Now let's assume I have two pistols: a Colt 45 Commander with a 4.25" barrel, and a Colt 45 New Agent with a 3" barrel.
I've assumed that I should carry my Commander whenever possible, because it will be more effective if I need it. That is, longer barrel = more velocity and more power, and therefore more penetration and terminal effectiveness.
But, I've been thinking...higher velocity usually results in more expansion, which actually REDUCES penetration. So, will my 3" New Agent provide more penetration than my 4.25", all other things being equal?
