The suppressor designs i have looked at, and they are for the most part rather rudimentary, have venting in the suppressor, so the suppressor acts as something like an extended barrel with limited venting.

If the revolver is increasing the pressure such that more is escaping the cylinder gap, than the internal barrel must also be at higher pressure so performance will not drop.

If you have a 4 inch barrel with a 6 inch external suppressor, at some point after 4 inches gas will be vented into the can. This will decrease pressure significantly compared to a 10 inch barrel. I don't see how this will cause more pressure at the gap than a 10 inch unvented barrel, although obviously more than a 4 inch barrel. You would likely get the ballistic performance of something like, IDK, an 8 inch barrel out of the 4 inch + 6inch suppressor(I don't really have any idea behind a number between 4 and 10).
