Not one bit of difference between them. You cannot determine caliber by autopsy, wound channels all look exactly alike. Now, you CAN tell the difference between hardball or hollowpoints, but that's just about it.
I carried a 9mm for years, switched to a .45 just a couple of months ago, though not for caliber reasons, I just want an all stainless duty gun.
My caliber of choice in gunfights is 5.56 mm anyway.:D
Don't try and outweird me, I find weirder things than you in my breakfast burrito.
