wow - not sure I understand some of the terms you used, but interesting stuff. My conclusion is that barrel length > about 15" out to 24" lead to a 5% velocity LOSS = about a 10% muzzle energy loss. Thus these longer barrels are a negative not a positive in pistol calibers. Am I thinking about this correctly? thanks - tom
