New In Box RUGER GP 100 Double-Action Revolver, Model KGPF-341, 357 Remington MagCaliber, 4" Barrel, Stainless Finish, Full Shroud, Wood GripsThe sophisticated engineering in Ruger double-action revolvers isevident not only in how they are put together, but in how quickly theycan be disassembled. Composed of a series of integrated subassemblies,the GP100 and SP101 can be fieldstripped to their basic components inseconds for cleaning without the use of tools. Ruger's philosophy ofstrength, simplicity, and ease of maintenance has been appliedthroughout.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 notchesare offset and cut into the thick part of the cylinder walls betweenthe centers of the chambers rather than directly over them. In itsfiring position, the cylinder is securely locked to the frame in twoplaces: at the rear by the traditional cylinder pin, and at the frontof the crane by a large, unique spring-loaded latch. This helps ensureproper cylinder and barrel alignment for optimum accuracy.
