That's true--but another 100-150 fps for a pistol bullet is still significant--given their relative ballistic inefficiency and how fast they loose energy.
You are only going to see a gain of about 50fps for the extra 8" of barrel.

6 or 8 inches longer of barrel for 20 to 40 fps more is not worth the added length to the gun or decreased rigidity.
Exactly.

My rifle and pistol are tools, I am the weapon.
I don't have a 8.5" barrel to compare with--I was running the numbers through QL. I'd be very interested to compare results using a known factory ammo just out of curiosity.
