Common Sig M11-A1 Problems And Solutions
Some of the common problems and solution below
1. Trigger Pull Problem
If you own the SIG Sauer M11-A1 pistol, then you’re likely familiar with the trigger pull issue many owners experience.
This issue can be a major issue for any shooter, regardless of skill level, and can prevent you from getting the most out of your firearm. Fortunately, there are ways to diagnose and fix your weapon’s trigger pull issue.
This issue is usually caused by the trigger spring being either too weak or too strong.
The spring is what gives the trigger its resistance, so if it’s too weak, then the trigger won’t have enough resistance and that can cause a heavy trigger pull. If the spring is too strong, the trigger will be too stiff, making it difficult to pull.
Fortunately, there is a way to diagnose and fix the trigger pull problem on your SIG Sauer M11-A1. The first step is to determine if the spring is too weak or too strong.
To do this, you’ll need to remove the slide from the frame and then remove the trigger housing from the slide. Once you have the trigger housing off, you can then inspect the trigger spring.
If the spring looks too weak, you’ll need to replace it with a stronger one. You can purchase a stronger spring from your local gun store or online retailers.
If the spring looks too strong, you’ll need to remove some of the coils to make it weaker.
Once you’ve determined the correct strength of the spring, you can then reassemble the trigger housing and reattach the slide. After that, you should be able to test the trigger pull and make sure it’s at the desired weight.
The trigger pull issue on the SIG Sauer M11-A1 can be a major issue for some shooters, but it can be fixed with a bit of time and effort. All you need to do is determine the cause of the problem, replace or adjust the spring accordingly, and then test the trigger pull to make sure it’s at the desired weight
2. Sliding Barrel Problem
The SIG M11-A1 is a popular handgun, but unfortunately, it’s prone to experiencing an issue with the sliding barrel. This problem is caused by the handgun’s design, which includes a rotating barrel.
The rotating barrel can bind, causing the gun to jam. This issue is most common when the handgun is fired multiple times in rapid succession. So, what can you do to fix this issue?
Fortunately, the solution is relatively simple. All you need to do is lubricate the barrel and slide. This will help reduce friction and prevent the barrel from binding.
Additionally, we recommend that you thoroughly clean the barrel and slide on a regular basis. In addition to lubricating and cleaning the barrel and slide, you may also want to adjust the tension screw.
This screw is located just below the rear sight, and it helps to adjust the tension of the barrel. The barrel may bind if the tension is too tight, resulting in a jam.
You may need to adjust this screw if you experience the SIG M11-A1 sliding barrel problem. Finally, you can always send your handgun in for service if all else fails.
Fortunately, SIG offers a lifetime warranty on their handguns, so you won’t have to pay for any repairs.
3. Sight Alignment Problems
Are you having trouble with Sig M11-A1 sight alignment? If so, you’re not alone. The Sig M11-A1 is a popular handgun with a reputation for accuracy, but getting the sights properly aligned for the best shooting performance can be difficult.
First, let’s start with the basics. The Sig M11-A1 is a double-action/single-action pistol that uses a three-dot sight system. The front sight is a blade-type, while the rear sight is an adjustable U-notch.
The sights should be aligned so that the dots or U-notches are all in the same plane when viewed from the shooter’s eye.
The gun will not shoot accurately if the sights are not properly aligned. One of the most common sight alignment problems with the Sig M11-A1 is the front sight being too high or too low.
If the front sight is too high, it will cause the point of impact to be too low, and vice versa. To adjust the front sight, use a sight adjustment tool to loosen the set screw on the bottom of the sight.
Then, turn the sight in the direction needed to raise or lower the front sight until it is properly aligned. Another common issue with the Sig M11-A1 is the rear sight not adjusting correctly.
The rear sight won’t move in either direction if it is too tight. To fix this, check the tension on the adjuster screw and make sure it’s not too tight.
If it is, loosen the screw slightly and try to adjust the sight again. If the sight still won’t move, try lubricating the adjustment screw with a drop of gun oil. Finally, it’s important to make sure that the sight picture is clear and free of obstructions.
Check the front sight blade to make sure it isn’t bent or damaged, and make sure there are no obstructions in the rear sight notch. If there are, use a fine needle file to remove any obstructions and make sure the sight picture is clear.
4. Failure To Extract
Another common problem with the SIG M11-A1 is Failure to Extract (FTE). FTE is a recurring issue with this particular model and can be a major source of frustration.
What is Failure to Extract?
Failure to Extract (FTE) is a malfunction of the SIG M11 A1 military gun where the slide fails to move backwards in order to eject a spent shell casing.
As a result, the spent shell casing will remain in the chamber and will not be extracted. This can lead to a stoppage of the action and cause further malfunctions.
What Causes Failure to Extract?
There are several possible causes for FTE with the SIG M11-A1. Some of the most common reasons include:
• Weak or worn extractor spring
• Damaged extractor
• Faulty magazine
• Improperly lubricated parts
• Dirty ammunition
• Out-of-specification parts
• Improper headspace
How to Fix Failure to Extract
When it comes to fixing FTE with the SIG M11-A1, it’s important to understand the cause of the issue. Once you determine the cause, you can move forward with the necessary steps to repair the issue.
1. Inspect the Extractor: Begin by checking the extractor to ensure it is in proper working condition. Look for any signs of damage or wear and replace it as necessary.
2. Replace the Extractor Spring: If the extractor appears to be in good condition, you will then want to replace the extractor spring. This process is fairly simple and can be done with a replacement part.
3. Inspect the Magazine: Next, you should inspect the magazine to make sure it is in good working condition. Look for any signs of damage or wear and replace it as necessary.
4. Clean and Lubricate Parts: Once you have replaced any worn or damaged parts, you should clean and lubricate all the working parts of the SIG M11-A1. This will ensure that all parts are functioning properly.
5. Test Fire the Gun: After all the necessary repairs and maintenance have been completed, you should test fire the gun to ensure that FTE is no longer present.
5. Not Returning To Battery
First, it’s important to understand what is causing this issue. The most likely cause is that the recoil spring has become worn and can no longer return the slide to the battery.
The recoil spring returns the slide to the battery after firing, so keeping it in good condition is important. If it’s worn or damaged, it will prevent the gun from returning to battery.
The next step is to check the gun’s tolerances to make sure that everything is within spec. If the slide is not returning to the battery, it could be because there is just too much play in the slide. A worn or loose slide stop can cause this, a worn or loose extractor, or a worn or loose firing pin stop.
Finally, inspecting the recoil spring for any signs of wear or damage is important. If it is worn or damaged, it must be replaced with a new one.
Replacing the recoil spring is not difficult and is usually done with a few simple tools. However, it’s important to get the correct springs for the model of gun that you have.
6. Magazine Rattling Issues
This can be annoying since the rattling sound can be quite loud and distracting. Fortunately, a few simple solutions can help you fix the issue.
First, loose magazine springs are the most common cause of magazine rattling issues. The springs are responsible for keeping the magazine securely in place, so if they are loose, then the magazine will move around and cause rattling.
To fix this problem, you should check the tension of your magazine springs and make sure they are tight. If you don’t feel comfortable doing this yourself, you can take your pistol to a gunsmith who can do it for you.
Second, the magazine catch may be worn or loose. The magazine catch is responsible for keeping it securely in place, so if it is worn or loose, it will allow it to move around and cause rattling.
To fix this issue, you should check the tension of your magazine catch and make sure it is tight. If it is not, then you should replace it.
Third, the magazine may be out of alignment with the frame. If the magazine is not correctly aligned with the frame, then it can move around and cause rattling.
To fix this problem, you should check the alignment of your magazine and make sure it is correct. If not, you should take your pistol to a gunsmith who can properly align it.
Finally, the magazine may be worn or damaged. If the magazine is worn or damaged, then it can move around and cause rattling. Inspect your magazine for any signs of wear or damage to fix this issue. If it is worn or damaged, then you should replace it.
7. Reliability Issues
The main cause of reliability issues with the M11-A1 is the lack of proper maintenance and cleaning. Like any other firearm, the M11-A1 needs to be consistently cleaned and lubricated to perform optimally.
As with any firearm, dirt, debris and other foreign material can cause malfunctions and stoppages. Disassembling and cleaning the M11-A1 at least once a month is important to remove any build-up. Another common cause of reliability issues with the M11-A1 is incorrect ammunition.
The use of incorrect ammunition can cause the M11-A1 to malfunction. It is important to always use the correct ammunition for your M11-A1, as this is a major cause of reliability issues.
One of the best solutions to ensure the reliable operation of your M11-A1 is to use quality parts and components. Quality parts and components will ensure reliable operation and reduce the likelihood of malfunctions and stoppages.
Finally, having your M11-A1 inspected by a qualified armorer every few years is important. This is especially true if you use the firearm extensively. Even an armorer can inspect the M11-A1 for worn or damaged parts and replace them if necessary. This can help ensure that your M11-A1 remains reliable for years to come.
