Common Smith And Wesson M&P 10mm Problems And Their Solutions

1. Failure To Feed

You’re not alone if your M&P 10mm is experiencing “failure to feed” errors. This issue has been known to occur in several models of the 10mm and can be extremely frustrating.

First, check the recoil spring assembly. If the tension on the slide is too high or too low, it can cause a failure to feed malfunction because it affects how smoothly and reliably the ammunition is fed into the chamber from the magazine.

Recoil springs are designed to be replaced regularly, so if you’ve been using the same spring for years, it may be time to invest in a new one.

Second, make sure that your magazine is clean and functioning correctly. Dirt or debris can build up over time and impede the feed lip from moving freely when rounds are loaded into the chamber. This can cause jams and misfeeding.

Be sure to inspect your magazine for any dirt or debris, and if necessary, you can use a cleaning solution to ensure it is functioning properly.

Finally, when all else fails, try using a different brand of ammunition. Different brands are loaded differently and have case dimensions that vary slightly from one another- so if your M&P 10mm isn’t feeding your current ammunition reliably, switching to another brand may help the issue.

2. Recoil Spring Issue

One common issue some M&P 10mm owners have reported is a recoil spring issue. This issue can cause the pistol’s slide not to lock back after the last round has been fired.

The recoil spring is a key component of all semi-automatic guns. It helps absorb the gun’s energy when it is fired and in turn, cycles the action back into battery.

Over time, it can become weakened or worn out due to use and must be replaced with a new one.

Fortunately, replacing the recoil spring on an M&P 10mm is a relatively easy process. You will need to obtain the correct recoil spring for your gun, and then remove the existing one.

Be cautious when removing the old spring, as it can be under tension and dangerous if not handled properly.

3. Slide Fails to Return to Battery

It’s important to take the time to inspect your gun regularly and pay attention for signs that indicate a problem is occurring.

If you start noticing your gun jamming, having difficulty chambering rounds or returning to the battery, it’s important to look into it and fix any issues as soon as possible.

The first thing to do when diagnosing this issue is make sure that all of your parts are in good condition.

Ensure the slide and frame aren’t too worn out or misaligned and check for any dirt or debris causing an obstruction. Also, ensure the firing pin block isn’t sticking or malfunctioning.

If you can’t find the cause of the problem after inspection, it’s important to take your gun to a certified gunsmith.

4. Failure To Fire

If your M&P 10mm has trouble firing, there are a few possible causes. First, the gun could be dirty or need lubrication.

This can lead to irregular or incomplete rounds being fired from the chamber. Second, you may have the wrong ammunition in the magazine.

 Ensure you’re using the correct caliber of round for your handgun. Finally, you may need to replace the firing pin or springs in the gun. Contact your local Smith and Wesson service center for assistance if all else fails.

It’s also important to ensure you use the correct grip while shooting. A proper grip will place your finger on the trigger at just the right angle, helping to prevent any misfires.

5. Magazine Issue

If you are experiencing loading issues with your S&W M&P 10mm, it’s important to understand the cause of the problem before attempting any DIY fixes or repairs.

It could be an issue with the magazine itself, such as a broken spring, or it could be due to a foreign object blocking the feed lips on the magazine such as dirt or debris.

Once you determine what’s causing the issue, cleaning and lubricating the magazine may help to resolve the issue.

If it’s a more serious problem, you might need to replace or repair the magazine components for optimal performance.

If your M&P 10mm is having trouble dropping free from the frame, then several issues could be at play, causing this malfunction.

 Ensure that all of your pistol’s parts are properly lubricated, and inspect for any signs of wear or damage that could prevent the magazine from dropping free. Depending on the issue, you may need to replace your magazine catch if it’s damaged or worn down.

6. Trigger Issues

Common issues with the Smith And Wesson M&P 10mm triggers include light strikes, accidental double-action fire, misaligned trigger bar/sear, and a gritty feel.

Several things, including worn or broken parts, incorrect assembly procedures, or lack of cleaning and lubrication, can cause these issues.

If your 10mm has an issue with light strikes, the first thing to check is that the firing pin safety plunger spring is correctly installed and working.

If not, this can cause light strikes since the firing pin safety plunger is not pushing up on the back of the pin as intended.

Checking the trigger bar/sear assembly is a good next step. For starters, ensure all components are in good condition (e.g., no cracks or deformities in the bar).

Ensure the bar and sear are in the correct orientation when assembling. If all looks good, check the engagement between the bar and sear for any binding or play.

Finally, properly lubricate your 10mm with a high-quality firearm oil or grease. This should help reduce any gritty feel and wear on moving components over time.
