Reliability Under the Microscope: Common Issues and Resolutions
The Frustrating Failure to Feed
A failure to feed (FTF) is when a round fails to chamber fully, halting the firing sequence. This can be a frustrating and potentially dangerous situation, particularly in self-defense scenarios. The M&P 9mm Pro Series, like any semi-automatic pistol, can experience this issue. The causes are often related to a combination of factors.
One area of concern can be magazine-related problems. Magazines are subjected to constant use and wear. The magazine spring, which pushes rounds upward, can weaken over time, leading to insufficient force to chamber the next round. Damaged magazine lips, those small protrusions that hold the rounds, can also prevent proper feeding. Furthermore, ensure the magazine is compatible with your specific model. While the core design of M&P magazines is generally consistent, subtle variations can occur.
Another contributor to FTF issues can be ammunition-related problems. The type of ammunition used can significantly impact the functioning of a firearm. Using low-quality ammunition, reloads (ammunition that is reloaded), or ammunition that does not meet the proper specifications, can introduce inconsistencies that lead to FTF. These rounds might not be perfectly dimensioned, have insufficient powder loads, or generate inconsistent pressures, all contributing to a malfunction. Always use high-quality, factory-loaded ammunition that is appropriate for your M&P 9mm Pro Series, and inspect each round before loading.
Finally, sometimes, ramp or barrel issues can contribute to FTF. The feed ramp, the angled surface leading into the chamber, guides the bullet into the chamber. A rough or unpolished feed ramp can impede the bullet’s movement. Similarly, issues within the barrel itself can cause FTF, although these are less common.
Addressing FTF typically starts with a thorough examination. Inspect your magazines for damage or wear. Replace any magazines showing signs of wear. Clean your magazines. Secondly, experiment with different ammunition brands and bullet weights to identify any potential compatibility issues. If the problem persists, consider polishing the feed ramp (if you have the mechanical aptitude or taking it to a qualified gunsmith).
The Extraction Conundrum: Failures to Extract
A failure to extract (FTE) occurs when the spent casing remains stuck in the chamber, preventing the next round from loading. This is another common malfunction in semi-automatic handguns, and the M&P 9mm Pro Series is not immune. FTE issues are often more complex, involving multiple factors.
The extractor, a small hook-shaped part that grabs the rim of the spent casing, plays a crucial role in extraction. Wear, damage, or insufficient tension of the extractor are frequent causes of FTE. Over time, the extractor can wear down, losing its grip on the casing rim. It can also be damaged by excessive force or poor maintenance.
Chamber issues can also lead to FTE. A dirty or rough chamber can grip the spent casing, preventing it from easily sliding out. Carbon buildup, dirt, or rust can create friction, causing the casing to stick. Proper cleaning and lubrication of the chamber are therefore essential.
Ammunition can also play a role, as with FTF. Ammunition with excessive pressures or casings that are out of spec can cause the spent casing to be difficult to extract. Again, high-quality ammunition will significantly mitigate these risks.
Troubleshooting FTE usually involves a systematic approach. First, inspect the extractor for damage or excessive wear. If it shows signs of wear, replacement is recommended. Next, thoroughly clean the chamber, using a dedicated chamber brush to remove any carbon buildup or debris. Finally, make sure you are using quality ammunition.
Stove Piping: A More Dramatic Malfunction
Stove piping, where the spent casing gets trapped partially in the ejection port, resembling a stovepipe, is another type of malfunction. While technically a variant of FTE, it presents its own unique troubleshooting requirements.
The causes of stove piping are generally similar to those of FTE. Issues related to the extractor, chamber, or ammunition are often to blame. A weak extractor might fail to pull the casing far enough, leading it to get caught in the ejection port. A dirty chamber might grip the casing, preventing a clean ejection. Finally, inconsistent ammunition can lead to insufficient gas pressure to cycle the action correctly.
Resolving stove piping often involves the same procedures as addressing FTE. Examine and potentially replace the extractor. Clean the chamber thoroughly. And, again, utilize high-quality ammunition. Proper shooting technique also is important.
Ergonomics and Design: Shaping the Shooting Experience
Beyond reliability, the feel and functionality of a handgun are critical. The M&P 9mm Pro Series offers specific ergonomic characteristics. Understanding these features and their potential drawbacks is crucial for shooters.
The Trigger: A Key Element
The trigger mechanism significantly affects the shooting experience. The M&P 9mm Pro Series utilizes a trigger system that has both advantages and disadvantages.
One common area of concern is the trigger pull. Some shooters find the trigger pull weight of the M&P Pro Series to be a bit heavy. This can make it more challenging to achieve accurate shot placement, especially at longer distances. Another common criticism is that some shooters have said the triggers in the M&P Pro Series had a “gritty” or “rough” feel. This can impact how smoothly the trigger moves, and some gun owners have found the quality of the trigger in the M&P Pro Series to not be up to the standard of similar firearms. Furthermore, a trigger has a reset, and the trigger reset on the M&P Pro Series has been described by some shooters to be “long”.
Fortunately, many aftermarket options exist to improve the trigger. Trigger upgrade kits can reduce the trigger pull weight, smooth out the pull, and shorten the reset. The investment is well worth it for some shooters.
Grip and Handling: A Personalized Fit
The M&P 9mm Pro Series is designed with a grip that has a specific shape, size, and feel.
Grip size is a matter of personal preference and hand size. Some shooters with smaller hands may find the grip to be slightly too large, making it more difficult to get a secure grip and properly manipulate the controls. Conversely, shooters with larger hands might find the grip to be comfortable. The modular backstraps (interchangeable grip panels) that come with the M&P Pro Series aim to address this issue by allowing users to customize the grip to better fit their hand size.
Grip modifications are also an option. Adding grip tape or wrapping the grip in stippling can improve grip. Ultimately, the goal is to achieve a secure, comfortable, and consistent grip.
Maintenance and the Test of Time
Keeping your M&P 9mm Pro Series running in peak condition requires proper maintenance. The following highlights some important aspects.
The Ritual of Cleaning
Regular cleaning and lubrication are essential. Disassemble the firearm according to the manufacturer’s instructions. Then, use a cleaning rod, bore brush, and solvent to remove carbon buildup and debris from the barrel and chamber. Use a quality gun cleaner on the frame, slide, and other parts. After cleaning, apply a light coat of gun oil to all moving parts, including the rails, slide, and trigger components. Wipe off any excess oil. Proper lubrication reduces friction, minimizes wear, and helps prevent malfunctions. Neglecting this routine can eventually lead to reliability issues.
Wear and Tear: Knowing What to Expect
All firearms experience wear and tear over time. The M&P 9mm Pro Series is built to last, but certain parts are subject to wear and might need replacement. Springs, such as the recoil spring, magazine springs, and trigger springs, are especially susceptible to wear and should be inspected regularly. The extractor may also wear down with use. You may eventually want to take your M&P 9mm Pro Series to a gunsmith to examine the firearm. The rate of wear depends on factors such as the frequency of use, the type of ammunition, and the quality of maintenance.
Comparison and Alternatives: Considering the Competition
The M&P 9mm Pro Series exists within a crowded market.
Compared to other popular handguns, such as Glock or Sig Sauer, the M&P 9mm Pro Series has a distinct set of advantages. The M&P’s ergonomics, specifically the grip angle and the ability to swap grip inserts, often lead to it being called a more comfortable handgun to hold. However, the M&P has been critiqued for having a trigger that is not as good as other firearms in its category.
In Conclusion: Weighing the Benefits and Drawbacks
The M And P 9mm Pro Series problems are important for anyone considering or owning this handgun. It’s essential to know about all the potential problems, such as FTF, FTE, and stove piping, along with the remedies. The design, while generally praised, has some weaknesses. While the trigger, in particular, receives mixed reviews, and the grip may not be ideal for all hand sizes, these are often issues that can be fixed.
