Lists on the subject

The Walther GSP (utility standard pistol ) is a modular sports pistol , which is manufactured by the Carl Walther company in different versions. It is probably the best-selling sport pistol in the world.

The pistol was specially developed for shooting sports in 1968 and its design makes use of all the possibilities of the competition regulations.

The special feature of this sport pistol is that thanks to the modular structure it has meanwhile become

• 3 different calibers
• 3 different trigger options and
• 4 different shaped handles

be available.

Since the possession of weapons is also regulated in terms of quantity under German law, this system offers the possibility of owning three weapons in one and thus being able to participate in a wide variety of sports disciplines.

construction

The basis for the Walther GSP is an aluminum handle. Four holding elements are integrated in this handle. The magazine catch is attached in the middle of the magazine shaft and works by means of spring pressure. A retaining lever on the left side of the weapon locks the bolt housing, which is otherwise only pushed on, via a half shaft. A shaft that can also be operated from the left (but with a screwdriver) fixes the trigger unit of the OSP trigger. The slide catch lever is located on the right-hand side and holds the slide in the open position. It can only be operated manually. The wooden handle is attached to the rear of the handle.

The trigger unit is inserted into the handle from above. An additional plastic shell covers the inside of the trigger guard. If the GSP trigger is used, it is fixed in the handle using a screw located on the rear / top of the trigger unit.

The system consists of the bolt housing, which houses the bolt with firing pin, ejector and bolt spring. The clamping piece is guided through a slot in the breech block and two slots in the breech block housing so that the shooter can tighten the breech block. In the variant in caliber .32 S&W long WC, the clamping piece is enlarged so that the locking mass increases. The rear sight is also located on the housing.

The barrel is inserted into the breech block housing from the front and fixed with a screw. The front sight and possibly a barrel weight are on the barrel.

The scope of delivery includes, depending on the version, 2 magazines, tools and a case.

While the first weapons still had a manual safety device , various changes were made in the next generation (from weapon no. 67 001, built in 1978).

These included a. the omission of the fuse, a flattening of the system, shortening of the barrel, changes to the handle design and sights as well as changes e.g. B. on the springs. From this date onwards all grips, systems and trigger systems were really interchangeable.

In the current GSP Expert , the barrel has been lengthened to 115 mm and at the same time (only in caliber .22 lfB) encased in plastic. This is to prevent undesirable vibrations when firing a shot. The blue anodized aluminum barrel weight contains two movably mounted metal pins each weighing 17 g. These are held in place by springs and serve as absorbers for the recoil of the weapon. However, the compensator slots are only intended to enhance the appearance and have no function.

The fastener, which is hardly affected by any signs of wear, was coated with hard material (nitrocarbonated) to reduce frictional resistance.

The handle made of natural-colored and blue plywood has been redesigned and is available in three sizes for right-handers and in a left-hand version.

A version equipped with manual backup is also available for export to the USA.

The Walther OSP was designed for the Olympic rapid fire pistol as early as 1961. If not just an interchangeable system but the complete weapon is purchased, the grip is a little lighter than that of the GSP and has a Morini grip that extends over the back of the shooter's hand.

The rear sight is attached to the rear end of the system so that the length of the sight is more than 5 cm longer than that of the GSP. At the same time, the distance between the barrel axis and the sight axis is also smaller. The barrel length of this weapon in .22 caliber short is only 85 mm. Boreholes in the area of ​​the barrel near the muzzle prevent the weapon from turning up when a shot is fired.

The weak cartridge .22 short enables 5 shots to be fired at 5 different targets in quick succession. Therefore, in this discipline, a trigger weight of a maximum of 200 g is used.

Adaptation of the weapon to the shooter

In addition to the now four different handle types (S, M, L and left-handed) that can palm rest can be adjusted in height.

The sight can be adjusted in height and side using two screws in the area of ​​the rear sight. If a shooter cannot cope with the size of the rear sight or front sight, different sizes of rear sight and front sight are available.

So that you can quickly switch between the disciplines "Duel" (large mirror) and "Precision" (small mirror) in which "mirror mounted" is shot, there is also a front sight that can be adjusted in two height positions, called a folding front sight.

There are four different trigger systems for the GSP / OSP. In addition to a training trigger, there are 1,000 g, 1,360 g and 200 g prints. These can be exchanged within a few seconds. The OSP trigger system can be easily recognized by the fact that the trigger tongue is attached to the bottom of the handle, while the GSP trigger acts axially backwards.

The trigger itself can then be continuously adjusted for both the pull-in force and the pressure point force.

The trigger path, position and angle of the trigger are also adjustable.
