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.
