WALTHER PDP OPTIC PLATE STRESS TEST
Below is information on the Walther PDP optic plate stress test and round count.
We diligently conducted Walther PDP optic plate stress tests. The highest stress/load for the slide and all mounted parts results from the acceleration of the slide while firing. The acceleration can go up to 1800 G. The force on the Adapter Plate resulting from this effect is transferred over the Pressing Face from the Adapter Plate to the Slide. This design ensures that the Adapter plate is always pressed against this transfer Surface.
The negative acceleration in the opposite direction is extremely small. The force in this direction can be held easily by the screws combined with the friction between the optic mounting Adapter Plate and the Slide.
- Two pistols were chosen. Each had 10,000 rounds shot with mounted Red Dot. No maintenance performed on the plates during the 10,000 rounds. No issues appeared, no loose screws.
- One pistol was chosen and had 20,000 rounds shot with mounted Red Dot. No maintenance performed on the plates during the 10,000 rounds. No issues appeared, no loose screws.
- One pistol was chosen and had 50,000 rounds shot with different versions of Red Dot sights and their corresponding adapter plates. While the same Red Dot and Mounting Plate were mounted, no maintenance at the plates was done, no issues appeared, no loose screws.
