The Smith & Wesson M&P 9mm Pro Series is a popular choice among both law enforcement and civilian shooters. Known for its reliability and accuracy, it's not without its potential issues. This article delves into common problems reported by M&P 9mm Pro Series owners, offering troubleshooting tips and solutions. Understanding these potential issues can help you maintain your firearm and ensure its optimal performance.
Common Issues with the M&P 9mm Pro Series
While generally reliable, several problems can arise with the M&P 9mm Pro Series. These often stem from user error, ammunition issues, or occasionally, manufacturing defects. Let's examine some of the most frequently reported problems:
1. Failure to Feed/Extract
This is perhaps the most commonly reported issue. Failure to feed occurs when the firearm doesn't properly chamber a round from the magazine. Failure to extract prevents the spent casing from being ejected. Several factors can contribute to these issues:
- Magazine Issues: Worn or damaged magazines are a frequent culprit. Weak springs can fail to reliably push rounds into the chamber. Bent or damaged magazine followers can also interfere with proper feeding.
- Ammunition Problems: Using substandard or improperly lubricated ammunition can lead to feeding and extraction problems. The wrong type of ammunition (e.g., using +P+ ammunition in a firearm not rated for it) can also cause damage.
- Improper Cleaning: A dirty gun, especially one with a build-up of residue in the chamber and ejection port, can significantly impede reliable feeding and extraction.
- Recoil Spring Issues: A worn or weak recoil spring can hinder the cycling process, leading to malfunctions. This is particularly relevant in higher round count situations.
Troubleshooting:
- Inspect the magazine for damage or wear. Replace if necessary.
- Try different brands and types of ammunition.
- Thoroughly clean and lubricate the firearm.
- Inspect and replace the recoil spring if necessary. A qualified gunsmith can help determine if this is the issue.
2. Trigger Issues
Some users report issues with the trigger pull, including:
- Excessive Creep: A long, vague feeling before the break. This often stems from the trigger bar interaction.
- Trigger Reset Issues: Difficulty feeling the reset point, leading to potential double-feeds or misfires.
- Trigger Pinch: The trigger can sometimes pinch the shooter’s finger during the trigger stroke, particularly when the shooter isn't using proper technique.
Troubleshooting:
- Professional Tuning: For excessive creep or trigger reset issues, consider seeking a professional gunsmith for tuning. They can adjust the trigger mechanism for a smoother, more consistent pull.
- Proper Technique: If you're experiencing a trigger pinch, ensure you're using proper grip and trigger finger placement. Practice dry firing (with an empty chamber, of course!) to refine your technique.
3. Sight Issues
While the sights are generally well-regarded, some users report issues:
- Loose Sights: Over time, the sights can loosen, leading to zero drift. Regular checks and potential tightening may be needed.
- Sight Preference: Some shooters prefer different sights, leading to upgrades for personal preference.
Troubleshooting:
- Tightening: Use a sight tool to verify and tighten any loose sights.
- Upgrades: Consider upgrading to sights that better suit your individual needs and preferences (e.g., night sights, fiber optic sights).
4. Slide Issues (Racking Issues)
Difficulty racking the slide is another problem sometimes encountered:
- Stiff Slide: A new firearm might have a stiffer slide, requiring more force to rack. This often loosens up with use.
- Sticking: Build-up or debris can interfere with smooth slide movement.
Troubleshooting:
- Break-in Period: If the firearm is new, regular use will often alleviate stiffness.
- Cleaning: Thoroughly clean the firearm to ensure there are no obstructions preventing smooth slide movement.
Case Study: Addressing a Failure to Extract Issue
A local law enforcement officer experienced repeated failure to extract issues with his M&P 9mm Pro Series. After systematically checking all potential causes—ammunition type, magazine condition, and cleaning—he discovered a small piece of debris lodged in the ejection port. Removing the debris resolved the issue, highlighting the importance of regular cleaning.
Maintaining Your M&P 9mm Pro Series
Regular maintenance is crucial for preventing problems and ensuring the longevity of your firearm. Here are some key tips:
- Clean after each use: Remove all residue, especially from the chamber, feed ramp, and ejection port.
- Lubricate: Use a high-quality firearm lubricant on moving parts.
- Inspect magazines: Regularly check your magazines for damage or wear.
- Regular inspection: Periodically inspect your firearm for any signs of damage or wear.
By following these tips and addressing potential issues promptly, you can significantly increase the reliability and lifespan of your Smith & Wesson M&P 9mm Pro Series. Remember, consulting a qualified gunsmith for any issues you cannot resolve yourself is always recommended.
