7 DP-12 Shotgun Problems (Best Troubleshooting Tips)

If you’re like me, reliability is one of the first things you look at when determining the best firearm. This is where the DP-12 shotgun stands out. 

Over the many years I have used this gun in the woods, I can voucher this firearm for you. It’ insanely powerful.

However, I have encountered a couple of issues with it. 95% of these DP-12 gun problems are relatively easy to fix.

The solutions I share in this post will work relatively well for you as long as you have the right tools. 

Why I like DP-12 shotgun in the first place

For those not familiar with it, the DP-12 shotgun is the first ever double-barreled shotgun to exist on the market. Its high-quality design plays a role in its success.

The gun comes with dual barrels and two magazine tubes. It’s heavier, however, which isn’t a cup of tea for users wanting indoor combat. But it impresses at short ranges.

With two barrels, you can fire two rounds in quick succession. You can also switch to the second barrel if the first one jams.

Here are common DP-12 shotgun problems and solutions

Discerning shooters maintain that DP-12 shotgun shoots well but complain about various issues with it, including failure to feed and extract, ejector problems, firing pins problems, bolt problems, accuracy problems, and trigger problems.

Problem	Solution
Failure to feed	Use quality ammo, clean and inspect the feed components like the feed ramp.
Accuracy problems	Check the barrel and sights for damages and replace them if necessary
Ejector problems	Repair or replace the ejector spring
Failure to extract	Inspect and replace the extractor
Firing pin problems	Replace the firing pin
Bolt problems	Clean and lubricate the bolt assembly periodically
Trigger problems	Proper gun maintenance

Problem 1: Failure to feed

During testing, the first problem that implicated the overall performance is the frustrating issue of “Failure to Feed,” This is where your shotgun fails to load the next round properly.

When the gun malfunctions this way, your shooting rhythm is disrupted, leading to missed opportunities. This is one of the Tisas 1911 problems as well.

The causes could include:

• Ammunition issues: Low-quality or cheap ammo can often lead to feeding problems. Damaged ammunition also results in failure to feed and extract issues.
• Magazine problems: A dirty or malfunctioning magazine can impede the smooth feeding of rounds into the chamber.
• Dirty or fouled Components: Accumulated dirt, debris, or fouling in the feed ramp, chamber, or bolt sometimes obstructs the feeding process, causing failures.

Solution

• Use quality ammunition: Invest in high-end ammunition from reputable manufacturers. Avoid using old and damaged rounds.
• Inspect and clean magazines: Regularly clean your shotgun magazines whenever possible. Replace any damaged or worn-out components. Ensure that the springs are in good condition.
• Keep the shotgun clean and lubricated: Routinely clean and lubricate the vital parts of your firearm, including a feed ramp, chamber, and bolt. A well-maintained gun is less likely to experience feeding issues.

Problem 2: Accuracy problems

Every firearm owner cares about accurate shooting. If your shots with your DP-12 shotgun aren’t accurate, it’s crucial to pinpoint the underlying causes and find a solution.

The causes include:

• Barrel issues: Mostly a damaged barrel will significantly affect accuracy. Even minor defects can alter the trajectory of your shots.
• Sights and optics problems: Damaged or misaligned sights, optics, or scopes can cause your shots to miss off target.
• Shooter error: Sometimes, the problem may not lie with the shotgun itself but with the shooter’s technique. Improper stances can lead to accuracy issues.

Shooting inaccurately is among the biggest Glock 43x problems most users encounter.

Solution:

• Check the barrel: Inspect the barrel carefully for any defects, obstructions, or damage. If you find any issues, get it repaired or replace it with a new one.
• Proper sight alignment: Verify that your shotgun’s sights and optics are correctly aligned. Make necessary adjustments to maintain accuracy.
• Proper shooting techniques: Enroll in firearms training courses to improve your shooting skills. Correcting your shooting form can have a significant impact on accuracy.

Problem 3: Ejector problems

A reliable ejection system means a lot when it comes to efficient shooting. Ejector problems cause the spent shells not to clear the chamber properly, causing frustration. This is a common Glock 19X problem that I found as well.

Here are the causes:

• Ejector spring issues: Ejector springs can weaken over time, leading to inconsistent ejection of spent shells.
• Dirt and debris in the ejection port: Accumulated dirt in the ejection port can sometimes obstruct the ejection process.

Solution:

• Replace or repair the ejector spring: If you suspect a broken ejector spring, make a plan to replace or repair it. A functioning ejector spring is critical for reliable ejection.
• Clean the ejection port area regularly: Thorough cleaning of your firearm is worth it and should be a maintenance routine. Focus on the ejection port area mostly.

Problem 4: Failure to extract

Another downside of the DP-12 gun is the “Failure to extract problem.” The issue occurs when your shotgun struggles to remove the fired cartridge case from the chamber.

The causes behind this issue include:

• Extractor issues: A damaged extractor doesn’t grip the spent shell properly. This leads to extraction failures.
• Dirty chamber: A chamber fouled with dirt. It can also be corroded, impeding the smooth extraction of spent shells.

Solution

• Inspect the extractor: You need to inspect and replace the extractor if necessary. A working extractor ensures extraction reliability.
• Clean the chamber thoroughly: Use the appropriate cleaning tools and solvents to wipe out any residue buildup on the chamber. A clean chamber plays a vital role in smooth extraction.

Problem 5: Firing pin problems

The firing pin is an obvious component responsible for igniting the primer of the cartridge. When firing pin problems arise, the gun will likely misfire or fail to fire altogether.

The following are the causes:

• Worn firing pin: After using your gun for a while, firing pins become worn, rendering them ineffective.
• Weak hammer spring: Such a spring can’t provide sufficient force to strike the firing pin. Your gun will eventually misfire.

Solution

• Replace the firing pin: Just replace it with a new, functional one. You can seek help from a gunsmith.
• Check the hammer spring condition: Inspect the hammer spring for signs of weakness. If needed, replace it with a new spring to ensure reliable firing.

Problem 6: Bolt problems

A smoothly operating bolt ensures your gun functions per your shooting needs. When you’re encountering bolt-related issues, these could be the causes:

Common causes:

• Bolt binding: Misalignment can cause the bolt to bind during cycling, leading to malfunctions.
• Worn-out bolt components: Vital components of the bolt assembly can wear out after prolonged usage, affecting its reliability.

Solution

• Inspect bolt assembly: Regularly inspect the bolt assembly for signs of wear, misalignment, or dirt accumulation. Clean and lubricate it periodically.
• Replace finished bolt parts: Damaged components in the bolt assembly must be replaced with functional parts.

Problem 7: Trigger problems

A good trigger mechanism boosts safety and accuracy. Address trigger problems promptly to maintain control over your shotgun.

The causes are as follows:

• Trigger mechanism issues: Internal components of the trigger mechanism may malfunction, leading to these problems.
• Dirty trigger components: Accumulated dirt in the trigger mechanism can hinder its proper function.

Solution

• Seek professional gunsmith: Consult a qualified gunsmith for a thorough inspection and do any necessary repairs or replacements.
• Proper maintenance: The trigger assembly should be maintained. Cleaning is one way of increasing the lifespan of your gun.

Is the DP-12 shotgun worth buying despite these problems?

Yes. The DP-12 double-barrel shotgun is an impressive firearm. I fell in love with it and had to get one. The gun is designed to offer consistent reliability and extreme firepower.

However, like any other weapon stored in your gun safe, the Dp-12 Shotgun can develop problems that may hinder your shooting experience.

Some of the reasons why you should choose a DP-12 shotgun are:

• Features two barrels stacked on top of each other, allowing for quick succession shots.
• Offers a high level of ambidextrous operation.
• Its hefty weight ensures better recoil management.
• It has a high ammunition capacity with two magazine tubes that hold up to 16 rounds. This makes it ideal for hunting, home defense, shooting competitions and tactical situations.

Some shooters are willing to overlook the DP-12 shotgun problems.
