Which has the greatest/biggest muzzle flash? 9mm vs .40s&w vs .45
I havent been able to find much info about muzzle flash, but lemme tell you I hate it. I dont like giant fireballs in front of my face, it throws off my shooting and since I want to carry a gun I want the lowest flash for self D.

I know ammo can have alot to do with it, but I'm sure there is a general/standard muzzle flash for each caliber, i just dont know it, and I just would like to know your opinions on each. which has the biggest, least, etc.
