[edit] Features / Description

The GP-100 is manufactured in .357 Magnum and .38 Special versions (.357 models can fire .38 Special rounds, .38 Special +P, and .38 Special +P+)
Barrel lengths 3" (76mm), 4" (102mm) and 6" (152mm) with partial or full length underlugs. (Some special production runs of 5" barrels have also been done.)
Blued Steel, or Stainless Steel finish

* Stainless model numbers are preceded with a 'K'

Transfer bar safety mechanism

* Firing pin mounted in frame

* The Transfer bar in the GP-100 is connected directly to the trigger. The transfer bar must be present between the hammer and the firing pin in order for the cartridge to be fired. The transfer bar only assumes the required position when the trigger is pulled all the way back.

* Fixed sight designated by "F" suffix on model number

[edit] Specifications

Major sub units of GP 100 (KGP-141)

Weight 2.2 lbs (1000 g 4", 1300 g 6") The type of sights and barrel profile affect the weight of the revolver. These are representative weights in the most common configurations.
Barrel lengths 3" (76mm), 4" (102mm), 5" (127mm) and 6" (152mm) The run of 5" GP-100 revolvers was the result of a special request from a large distributor.
Double Action. That is, the standard models of the GP-100 may be fired by either cocking the hammer and subsequently pulling the trigger, or by merely pulling the trigger when the hammer is not cocked.
Maximum effective range: 55 to 110 yards (50 to 100 meters) depending on barrel length, cartridge load, and additional optical sights. Projectiles from this weapon can still be dangerous up to several thousand feet from the muzzle under optimum conditions. The quoted range is more a function of the useful range of a typical handgun than a statement of the maximum lethal range of the projectiles.
6-Shot
Triple cylinder lock. When the cylinder is closed and the gun is at the point of firing, the cylinder crane is locked into the frame at the front and rear of the crane and by the cylinder lock at the bottom of the crane opening.
Disassembles quite easily into three major modules with only limited use of tools. This allows the user to easily clean the revolver after shooting.
The design of the gun eliminates the need for a frame "sideplate", a feature which contributes to the GP-100's well-deserved reputation for strength.
