Common Walther PDP Problems And Their Solutions

1.  Failure To Feed

One of the most common problems with the Walther PDP is experiencing a “failure to feed” issue.

This occurs when the gun fails to properly load and chamber a new round from its magazine, making it impossible for you to fire your firearm until the problem has been corrected.

Several potential causes are behind this malfunction, ranging from an improperly seated magazine to a dirty or worn-out action. Fortunately, there are also numerous solutions that you can try in order to remedy the situation.

We first recommend ensuring your magazines are properly loaded and fully inserted into the gun. This will help ensure the rounds reach the chamber correctly when attempting to fire.

If your magazine was seated correctly, it may need to be cleaned, as dirt and debris can block the action from engaging properly.

You can use a cleaning solution or brush to remove any buildup and then lubricate the magazine for optimal performance.

If your gun still experiences intermittent failures after this, you may need to replace certain components, such as springs or firing pins due to wear and tear.

This can be done easily by contacting a certified gunsmith or taking the firearm to an authorized retailer for repair.

2. Trigger Reset Failure

Trigger reset failure is one of the most common problems experienced by users of Walther PDP pistols. The trigger fails to properly reset itself after each shot, leading to longer trigger pulls and slower follow-up shots.

Fortunately, a few simple steps can be taken to quickly address this issue and get your pistol back up and running at peak performance.

First, ensure your magazine is fully loaded and seated properly in the gun. If it is not, unload the magazine, insert it into the pistol frame, and press firmly downward until you hear a distinct click indicating it is locked in place.

Then check to make sure that the slide stop or thumb safety lever is being fully engaged when you pull the trigger.

Sometimes, the lever may not be fully pressed down when it should be, preventing the trigger from resetting itself properly.

If this is the case, press firmly until you feel a solid click indicating that the lever has been fully engaged.

Finally, check to ensure your recoil spring is installed and functioning correctly. If it is too old or worn out, replace it with a new one to ensure the gun is properly functioning.

3. The slide-stop issue

When the Walther PDP is fired, the slide stop can be pushed down by either the rearward motion of the slide or from recoil. When this occurs, it causes a malfunction requiring manual intervention.

You must use an upgraded slide-stop version with a longer arm to avoid this. This prevents it from being engaged during firing and eliminates the issue.

It is also important to note that this issue can be avoided by using other slide-stop designs, such as those with a pin that secures it.

In addition, you should adjust the tension of the slide-stop so that it does not move out of position while firing. Finally, ensure that all components are tightly secured and that the slide-stop is clean and debris-free.

4. Magazine Issue

One of the most common problems associated with Walthers is magazine issues. This can include magazines not locking in place properly or failing to drop free when the release button is pressed.

The causes for these issues vary widely, so it’s important to know what might be causing them before attempting any repairs.

Sometimes, the problem might be due to a damaged magazine component, such as a spring or follower.

Replacing the damaged part with an original Walther PDP-approved one is important if this is the case. In addition, make sure that the magazines are properly lubricated and functioning correctly.

Another potential cause of PDP magazine issues could be a worn-out magazine catch. If the catch is not properly engaging with the magazine, then it could be causing it to bind up in the gun’s frame.

Fortunately, this problem can usually be corrected by replacing the old catch with a new one.

Finally, if neither of these solutions works, there may be an issue with the magazine itself. If this is the case, contacting Walther PDP customer service for advice on rectifying the problem is best.

4. Optic mounting problem

Mounting plate fitment issues are probably the most commonly encountered problems with Walther PDPs.

The problem is that there isn’t a standard mounting plate for all optics, so some might not fit your particular model. To remedy this issue, purchase an aftermarket plate or find one that fits your gun.

Another issue with mounting plates is that they can be difficult to install. The process can take some patience and tinkering, as you may need to adjust the tension on the screws or loosen them to get a snug fit.

It’s also important to ensure that all necessary pieces, such as an Allen key or screwdriver, are included for the proper installation.

Finally, it’s important to ensure the mounting plate is properly secured before using your optic.

If the screws are too loose, the entire assembly will be at risk for shifting and moving when it’s not supposed to, leading to inaccuracy or worse.

Fortunately, this issue can be easily resolved by simply tightening the screws more securely.

5. Fitting Issue

Many users report having trouble when trying to fit a part into place due to its size or shape not matching up with the space available in the firearm. Fortunately, some steps can be taken to help solve this problem.

First and foremost, make sure that all parts are properly aligned and tightened down. This will ensure that the part is firmly secured, which is essential for proper functionality.

Next, if the firearm’s barrel has been removed or altered in some way, then it may be necessary to use a specialized tool such as an installation jig to help fit the part correctly into place.

Finally, it is important to ensure that the part being fitted is suitable for the particular make and model of firearm.

This includes size, shape, material type, and other design elements. If any of these criteria are not met, then the part may not be able to fit properly into place.

6. Firing Pin Issue

The firing pin issue on the firearm can be a tricky problem to identify and diagnose. The most common symptom of this problem is failure to fire rounds from the magazine, even when rounds are present in the chamber.

Additionally, you may experience light primer strikes or misfires if the firing pin becomes stuck.

Fortunately, there are several steps you can take to address this issue. First and most importantly, ensure the firing pin is clean and debris-free.

You can remove the firing pin assembly and inspect it for any dirt or obstruction preventing it from moving freely. Once you have cleaned the assembly, lubricate it with high-quality gun oil before reassembling it.

It’s also important to inspect the extractor for any damage or wear preventing it from pushing back far enough when a round is chambered. If you find any damage, you must replace the part before going further.

Finally, check the firing pin spring tension and adjust it if necessary. This can be done with either a screwdriver or a specialized firing pin spring tool.

If all else fails, you may need to seek the help of a gunsmith to address the firing pin issue further. A gunsmith can also provide valuable advice on how to keep your Walther PDP in tip-top shape!
