The Smith & Wesson M&P 9 Shield is a popular concealed carry pistol, known for its reliability and ease of use. However, like any firearm, it's not without potential problems. Understanding these potential issues can help owners troubleshoot problems, maintain their firearm properly, and ensure its continued safe and reliable operation. This guide explores some common concerns and offers solutions.
Common Smith & Wesson M&P 9 Shield Problems & Solutions
While the M&P 9 Shield boasts a robust design, certain issues can arise. These are often user-related or stem from a lack of proper maintenance.
1. Failure to Feed/Eject
This is perhaps the most frustrating issue with any semi-automatic pistol. Failures to feed or eject in the M&P 9 Shield can be caused by several factors:
- Ammunition: Using ammunition that is not properly lubricated, is of poor quality, or is not the correct caliber can significantly impact reliability. Sticking to reputable ammunition manufacturers and the recommended cartridge is key.
- Magazine Issues: Worn or damaged magazines can lead to feeding problems. Check for bent or broken feed lips, and ensure the magazine spring is strong and functioning correctly. Consider investing in extra magazines to rotate and maintain.
- Dirty Gun: A buildup of fouling (unburnt powder residue, lead, etc.) can interfere with the smooth operation of the firearm. Regular cleaning is essential.
- Improper Recoil Spring: A weak or damaged recoil spring can hinder proper cycling. While less common, it should be considered if other issues are ruled out.
Solutions: Use high-quality ammunition, inspect and maintain magazines, clean your firearm regularly, and, if necessary, consult a qualified gunsmith to check the recoil spring.
2. Light Primer Strikes
A light primer strike means the firing pin isn't striking the primer with enough force to detonate the cartridge. This can result from:
- Weak Ammunition: Some ammunition may have weaker primers. Switching brands can resolve this.
- Improper Trigger Pull: A rushed or improper trigger pull can lead to inconsistent firing pin strikes. Practice proper trigger technique.
- Dirty Firing Pin: A dirty firing pin channel can impede the firing pin's travel. Thorough cleaning is essential.
Solutions: Try different ammunition, practice consistent trigger control, and clean the firing pin and channel thoroughly. If the problem persists, a gunsmith should inspect the firearm.
3. Issues with the Slide Stop Lever
The slide stop lever can sometimes become difficult to engage or release. This is often due to:
- Dirt and Debris: Similar to other mechanisms, dirt buildup can interfere with the lever's function.
- Wear and Tear: Over time, the slide stop lever may wear, making operation less smooth.
Solutions: Thorough cleaning should resolve most issues. If the problem persists, consider consulting a gunsmith to assess wear and potential replacement.
4. Grip Issues
While subjective, some users find the grip angle or texture of the M&P 9 Shield uncomfortable. This is less of a malfunction and more a matter of personal preference.
Solutions: Consider aftermarket grips that offer different textures or angles to improve your comfort and control.
Maintaining Your Smith & Wesson M&P 9 Shield
Regular maintenance is critical for preventing many of the problems listed above. This includes:
- Regular Cleaning: Clean your firearm after each use, paying close attention to the barrel, chamber, and firing pin channel.
- Lubrication: Use a high-quality gun oil to lubricate moving parts.
- Inspection: Regularly inspect your firearm for any signs of wear and tear, including cracks, damage to the finish, and loose screws.
