This was a modification done to old stocks of Mark I’s and II’s after 27th April 1915 for the Royal Navy.
One of the problems with the Mark I was that the firing pin hole tended to burn out so the frame was modified to accept a replaceable hardened recoil shield instead of being part of the frame, this continued on all further models. It also rotated on a hollow tube axis making it almost frictionless and therefore very smooth, see photo. This was eliminated on the service revolvers by a collar at the rear of the axis pin and a nut sealing it. Another problem with top break self extracting revolvers was gas and powder fouling getting into the cylinder axis pin. Holster guides were added to stop snagging on the holster. It also saw the introduction of a special pawl to stop the rebounding hammer being knocked forward and discharged accidentally. The less components there were on the gun the less could go wrong, it was easier to maintain and cheaper to produce.
The lock was simplified using only five main components instead of nine to twelve as used in other revolvers. Being a powerful top break revolver it needed to be safe and strong this was achieved partly by the hammer hitting the stirrup latch before the pin hit the cartridge and either forced the latch closed or opened the gun either way the gun could not be fired without it being in a safe condition, this system was already in use on the WG revolvers.

The service revolver was a series of six models it was designed so that parts could be as interchangeable as possible to simplify repair and maintenance, even between different models.
