Most Common M&P 10mm Problems and Solutions

Now, let’s examine some of these problems and consider possible ways to address them.

1. Slide Fails to Return to Battery:

The slide does not fully return to the forward position after firing, causing feeding issues and preventing the firearm from cycling correctly.

If the slide fails to return to the battery, it may be due to various factors, such as a dirty or obstructed slide or frame rails, a weak recoil spring, worn-out or damaged slide components, or an issue with the barrel.


To get rid of slide failure to return to the battery, follow the steps below:

  • Clean the slide and frame rails, removing debris and fouling.
  • Make sure the recoil spring is seated correctly and not damaged or worn.
  • Inspect slide components for any wear or damage and replace them if needed.
  • Check the barrel for signs of damage or obstruction and take appropriate action.

2. Failure to Feed:

One frequently encountered issue with the M&P 10mm is a failure to feed properly. This occurs when the next round fails to enter the chamber during cycling.

The primary cause of failure to feed is often related to magazine issues. It could be due to improper loading, a faulty or worn-out magazine spring, or a misaligned follower.


To fix the problem with a magazine feed issue, follow these steps:

  • Ensure that the magazine is fully loaded with the appropriate ammunition.
  • Check for any debris or obstructions in the magazine.
  • Clean the magazine if necessary, removing any dirt, debris, or obstructions.
  • If the problem persists, consider replacing the magazine spring.
  • If you are unsure about replacing the spring or the issue remains unresolved, contact a professional gunsmith for further inspection and assistance.

3. Magazine Malfunctions:

Magazine malfunctions can include issues such as failure to lock in place, failure to drop free, or difficulty in loading rounds into the magazine.

Magazine malfunctions can be caused by a faulty magazine spring, worn-out or damaged magazine components, debris or obstructions within the magazine, or improper loading techniques.


To resolve any issues with the magazine, follow the steps below.:

  • Start by cleaning the magazine and ensuring there are no obstructions or debris.
  • Inspect the magazine components for wear or damage and replace them as needed.
  • If the magazine spring appears weak or worn, consider replacing it.
  • Ensure proper loading techniques, such as using the correct ammunition and following the manufacturer’s recommendations.

4. Recoil Spring Issue:

The recoil spring loses its strength or becomes fatigued over time, resulting in reduced slide cycling and potential feeding issues.

Recoil springs can experience wear and fatigue due to repeated use, exposure to heat, and environmental factors. The constant compression and release of the spring can cause it to weaken over time.


One potential fix for a recoil spring issue on an M&P 10mm is to install a stiffer spring.

Some shooters have had problems with the M&P 10mm not closing back up after ejection when using high-pressure 200-grain loads. This indicates that the company may have needed to optimize the gun for hotter ammunition.
