Common Girsan MC312 Problems And Their Solutions

1. Feeding Problems

Are you having trouble with your shotgun’s feeding mechanism? Do you find that your shotgun is failing to load properly, or that rounds are failing to eject?

These are all signs of feeding problems, a common issue that can plague even the most reliable of firearms.

There are a number of potential causes for feeding problems in shotguns. One possibility is that the magazine tube or action is dirty or clogged.

This can cause rounds to fail to feed properly, leading to malfunctions during firing. Another cause could be a damaged or worn down magazine spring, which can prevent rounds from being properly fed into the chamber and cause misfeeds.

Additionally, issues with the feed ramp or chamber can lead to feeding problems.

Fortunately, there are a number of steps you can take to address feeding problems in your shotgun.

First, ensure that your firearm is clean and well-maintained, with the magazine tube and action free of any dirt or debris.

If this does not solve the issue, consider replacing your magazine spring to ensure that rounds are properly fed into the chamber. In some cases, you may need to have your feed ramp or chamber repaired or replaced by a professional gunsmith.

2. Failed Lock After Last Fire

Another common problem with this shotgun is failed lock after last fire.

A failed lock after the last fire is a mechanical issue that occurs when the gun is fired, but the bolt fails to lock into position.

This can happen due to several reasons, including a damaged or broken firing pin, worn out parts, or a buildup of debris in the locking mechanism.

The main causes of a failed lock after the last fire can be several, including a damaged firing pin that does not engage properly, a lack of lubrication on the locking mechanism, a buildup of debris or dirt that interferes with the lock mechanism’s operation, or a broken or damaged part that needs to be replaced.

To fix this issue, you need to follow step-by-step instructions to ensure that your shotgun’s locking mechanism functions correctly.

The first step is to disassemble the shotgun and thoroughly clean all areas involved in the lock mechanism’s operation.

Then, you need to apply a lubricant precisely to the areas that need it and reassemble the shotgun. If the issue persists, replace the firing pin or any broken or damaged parts.

3. Misfires

When a misfire occurs, the shot does not go off or it fires with less force than expected, leading to poor accuracy and potential safety hazards. Misfires can be caused by various issues, so it’s important to identify the root cause and fix them properly.

One common cause of misfires is a dirty or clogged chamber. If the chamber is not cleaned regularly, residue can build up and obstruct the flow of gas, leading to misfires.

To fix this issue, you can clean the chamber using a bore brush or by using a gun cleaning solution.

Another cause of misfires is the use of low-quality ammunition. Some ammunition may not be compatible with your shotgun or lack proper ignition, leading to misfires.

To avoid this issue, make sure to use high-quality ammunition that is suitable for your shotgun.

Faulty firing pins or weak hammer springs can also cause misfires. These components are responsible for igniting the powder and firing the shot. If they are damaged or worn out, misfires can occur.

To fix this issue, you may need to replace the firing pin or the hammer spring.

4. Jamming Issue

The jamming issue is a common problem encountered by shotgun owners, and it can be a frustrating and time-consuming problem to deal with.

Fortunately, there are ways to fix this issue and prevent it from happening again.

There are several main causes for the jamming issue in shotguns. One of the most common causes is a failure to properly clean and maintain the firearm.

Dirt, debris, and fouling can accumulate in the gun’s barrel and action, causing the gun to fail to cycle and ultimately leading to a jam.

Another cause of jamming can be the use of low-quality, cheap ammunition. The cheaper ammunition often lacks consistency in its manufacturing, and as a result, can cause feeding and ejection issues in the firearm.

Worn or damaged parts in the shotgun can also cause jams. For example, a worn or damaged extractor or ejector can fail to remove spent shells from the chamber, leading to a jam.

To fix the jamming issue in a shotgun, the first step is always to clean and maintain the firearm properly. This includes not only regular cleaning but also proper lubrication and inspection of all moving parts.

If cheap or low-quality ammunition is the culprit, switching to a higher-quality brand can often prevent jams from occurring.

Replacing worn or damaged parts is also a fix for the jamming issue. A trained gunsmith can diagnose and replace the necessary parts, ensuring that the firearm is functioning properly.

5. Squib Fire

Have you ever heard of the term ‘Squib Fire’? For those who are unfamiliar with the term, Squib Fire is a dangerous phenomenon that can occur during the firing of a shotgun.

It is a type of misfire where the shotgun shell does not fully discharge and leaves behind a hot ember or debris that can ignite any unburned powder in the gun barrel causing a dangerous explosion. This often results in serious injuries or even death.

Several factors can cause Squib Fire, including a malfunctioning shotgun, insufficient cleaning or maintenance of the gun, damaged or defective ammunition, and operator error.

Operators can accidentally load the wrong ammunition into the gun or improperly handle the shotgun while firing causing a Squib Fire.

To avoid Squib Fire, there are a few simple steps that gun owners can take. Firstly, proper gun maintenance and cleaning is essential to prevent any malfunctioning of the gun.

The shotgun should be disassembled and cleaned after each use, and any damage or defects should be addressed before using the gun again.

Secondly, operators should be trained on properly handling the shotgun and be familiar with the ammunition they are using, to avoid mishandling or overpressure.

6. Light Striking

There could be several causes of this problem.

One of the most common reasons is a worn-out firing pin. Another reason could be a weak hammer spring. Additionally, the ammunition used may be of low quality or a wrong size.

Fortunately, the solution to this problem is relatively simple. Here are the steps to fix the issue of light striking with your Girvan mc312 firearm:

Step 1: Check Your Firing Pin

Examine your firearm’s firing pin. If it’s visibly worn out, it needs to be replaced.

Step 2: Inspect the Hammer Spring

Inspect the hammer spring to see if it’s weak. A weak hammer spring needs to be replaced as well.

Step 3: Use Quality Ammunition

Use good quality ammunition that is the right size for your firearm. It’s better to avoid cheap or reloaded ammo.

Step 4: Clean Your Firearm Regularly

Cleaning your firearm can prevent build-up of gunk and debris. These can impact the readiness of your firearm and cause light striking.
