While a heavier bullet increases the momentum for a given powder charge (or bullet energy), it would be mistaken to think that the pressure is decreased.

As explained in my post on Longer Barrels, the more massive the recoiling parts, the less recoil energy there is. With long barrel Lugers (with more mass), one will find that it eventually becomes impossible to automatically cycle the piece, regardless of springs, etc., simply because there is insufficient recoil energy.

Incidentally, it follows that the assisting spring in the forearm of the 02 carbine was an unnecessary design feature since the same function could have been performed with the mainspring (as demonstrated on the 12" Lugers without a forearm).
