Medium Frame
NOTICE: All Ruger double-action revolvers feature Ruger's Transfer Bar
Safety System. The transfer bar, raised into
firing position only as the trigger is pulled fully to the rear, transmits
the energy of the hammer blow to the firing pin.
The sophisticated engineering in Ruger double-action revolvers is evident
not only in how they are put together, but in how quickly they can be
disassembled. Composed of a series of integrated subassemblies, the GP100
and SP101 can be fieldstripped to their basic components in seconds for
cleaning without the use of tools. Ruger's philosophy of strength, simplicity,
and ease of maintenance has been applied throughout.
The GP100 and SP101 represent significant improvements over every other double-action
revolver available in the world today. Frame widths are
increased in critical areas that support the barrel; both frame sidewalls
are solid and integral sections of the frame, offering additional strength
and rigidity.
Cylinder-locking notches are offset and cut into the thick part of the cylinder
walls between the centers of the chambers rather than directly over them.
In
its firing position, the cylinder is securely locked to the frame in two places:
at the rear by the traditional cylinder pin, and at the front of the crane
by a large,
unique spring-loaded latch. This helps ensure proper cylinder and barrel alignment
for optimum accuracy.
