1 Trigger weight The Single-Action trigger weight is factory adjusted between 47.9 - 48.6oz (1360 1380g). With an external adjustment screw, the trigger weight can be individually adjusted between 35.2 - 70.4oz (1000 - 2000g). If your revolver is equipped with the match grip, the adjustment screw is intentionally hidden. As a result, the international sealing procedure during a match becomes a mute point.
Adjusting the Single-Action trigger weight Simultaneously Left side - hold the trigger spring stud screw Right side - loosen the secondary side screw, then adjust the trigger spring stud screw slightly and retighten the right side clamp screw. 3.3 Trigger stop The travel way of the trigger in the Single-Action mode is stopped by an adjustable trigger stop screw. This screw is located in the trigger guard behind the trigger. The protruding length of the trigger stop screw can be varied with the included .
Adjusting the trigger stop screw 4. Double-Action function In this mode, the hammer is cocked by pulling the trigger. The maximum trigger weight is 158.6oz (4500g = 44.15N). Rimfire weapons can have a slightly higher trigger weight. Please notice! During DA-(Double Action) mode, it is absolutely necessary that the trigger reaches its foremost position before you pull the trigger again.
For the technically trained customer, we will give a step-by-step explanation for the exchange of the roller. In general, we would prefer you to have this type of work done by your gunsmith or our certified Factory staff. 1. Remove the cylinder and grips. 2. Cock the hammer (#35), connect the hammer strut (#40) with hammer spring guide housing (#43). Use a hardened pin with a diameter of approx. .047" (1.2mm). For later models, the included .059"(1.5mm) Allen screw can be used.
the trigger is fully cocked. The proper function of the safety is directly connected to the correct movement of the trigger. A delayed trigger, e.g. due to a contamination or due to a trigger return spring that has been tensioned insufficiently, can influence the function of the safety. Please notice : Do not decrease the SA-trigger weight remarkably below 35.2oz (1000g), because not only the pre-travel, but also the function of the safety is influenced. 6.
hand (from the bottom right), through the window opening of the frame. The ejection rod can be operated with the thumb. Fixing the cylinder accelerates the unloading process. Furthermore, it will prevent the cylinder from falling back into the frame opening, and ergo keeping the employed ejector from hitting the frame. If this occurs, it might cause damage to the surface finish. While fixing the cylinder, the muzzle should always point downwards and/or in a safe direction.
Unloading the cylinder 7. Interchangeable cylinder The barrel material used for the weapons with interchangeable cylinders depends on the law restrictions for the nominal caliber. Precision losses due to compromises are not to be expected. Occasionally, minor changes in the position of the point of aim in both calibers may occur. This problem can be overcome easily by selecting the right ammunition or by adjusting the sights. The revolver in caliber .
Please be aware that a remaking of an interchangeable cylinder results in additional work and thus in additional expenses compared to the serial production. 8. Sight systems All our revolver models have elevation and windage adjustable sights. The adjustments are carried out by means of a screwdriver. Sights Model Combat / Model Sport / Model Target 8.1 Model Combat 8.1.1 Elevation adjustment A screw is inserted in the vertical axis of the sight, which can be accessed from the upper part of the sight.
When shooting left, the left screw has to be loosened (counter-clockwise) and the right side screw has to be tightened. When shooting to the right, the adjustment has to be done in the opposite order. 8.2 Model Sport 8.2.1 Elevation adjustment Elevation adjustment occurs via the elevation adjustment screw located in the sight. The elevation adjustment has a micrometer-click system. The elevation change of the sight is .0016"(.042mm) per click.
If your weapon is equipped with exchangeable rear sight blades, the elevation- and windage adjustment can be done by hand. This can also be facilitated by the use of a coin. A slight pressure on the upper side of the sight, done by e.g. the thumb, can relieve the elevation adjustment screw during this slight adjustment. The windage adjustment screw is located on the left side. Elevation and windage adjustment are effectively influenced by means of a micrometer-click screw. The sight physically moves .
If your weapon is equipped with an exchangeable front sight system, you have the option to change different front sights. Beyond the standard equipment, you can additionally order individually shaped sights. The exchangeable front sights are installed via an Allen screw located at the muzzle of the barrel. The screw in the barrel rib is unscrewed by approximately .158" (4mm) with the included .059" (1.5mm) Allen wrench. Then, the front sight can be taken out of the rib.
The barrel weight is installed underneath the barrel, by pushing it from the front at the bottom of the barrel shroud. However before attempting this, the attaching screws have to be backed off. The barrel shroud, as well as the surface of attachment have to be free of oil. To avoid damage of the barrel shroud, any dirt has to be removed. Then, the barrel weight can be pushed on the barrel shroud.
The action and all other movable elements should be oiled. Besides cleaning the functional parts, the surface of the weapon has to be cleaned and oiled as well. When using spray oil, a take down of the weapon is not necessary. Only use modern, water-impenetrable weapon oils with a low viscosity. Dirt can cause malfunctioning of the weapon. Avoid this by cleaning your weapon frequently and carefully. For example: Remaining dirt like unburned powder can easily get underneath the ejector during unloading.
our weapons has been proven worldwide in numerous tests. In addition to the construction features of the weapon and the exact manufacturing tolerances, the shooting performance is also determined by the ammunition employed. In order to give a statistically covered statement of the shooting performance of our weapon, numerous test series need to be performed. Single shooting results are therefore subjective. For this reason, we abstain from including an original target. 13.
