Types of Gun Jams
Before diving into the mechanics, it’s important to familiarize yourself with the different types of jams you might encounter. Recognizing the type of jam is the first step toward resolving it.
The failure of a firearm to feed a round into the chamber is a common and frustrating experience, known as a failure to feed (FTF). In this situation, the slide may cycle, but the next cartridge in the magazine fails to move into the correct position for firing. Several factors can contribute to this, which we’ll discuss later.
Another situation, the failure to fire (FTF), occurs when the trigger is pulled, and the firing pin strikes the primer, but the cartridge does not ignite. While this might seem straightforward, numerous underlying issues can cause this. This malfunction can leave you in a vulnerable position.
When a cartridge casing stubbornly refuses to leave the chamber after a round has been fired, we have a failure to extract (FTE). The spent casing remains lodged, preventing the next round from being chambered. This can stop the process mid-cycle, and you may have to physically remove it.
Conversely, a failure to eject (FTEj) happens when the spent casing does leave the chamber, but it is not ejected cleanly from the firearm. Instead, it may become trapped within the action, potentially causing further complications.
A particularly dangerous malfunction is the double feed. This happens when the firearm attempts to load a second round into the chamber before the first is ejected. This situation can lock up the firearm, requiring a more involved clearing procedure.
Lastly, a less common, but extremely dangerous issue is the squib load. This occurs when a cartridge doesn’t generate enough power to propel the bullet fully through the barrel. The bullet gets stuck, and firing another round immediately afterward can cause a catastrophic barrel rupture. This is one of the most critical malfunctions, as it can cause serious injury to the shooter.
Understanding the different types of jams is the foundation for effective troubleshooting. Each type points to specific potential causes, which we’ll now explore.
Mechanical Issues that Can Cause a Gun Jam
The mechanics of a firearm are intricate, and any slight deviation from perfect functionality can lead to a jam. A malfunction is not simply a random occurrence; it’s the result of a specific mechanical or environmental condition.
One crucial area is the ammunition itself. The quality, condition, and compatibility of your ammunition play a significant role in reliable functioning. Defective cartridges, those with dents, bulges, or other physical damage to the casing, can prevent proper chambering or cause extraction issues. It’s imperative to inspect each round before loading and to discard any that appear compromised.
Furthermore, using the incorrect ammunition type or caliber is a surefire way to induce a gun jam. A cartridge that doesn’t fit the chamber, or one with excessive dimensions, simply will not work. Even small variations in bullet weight or powder charge can impact reliability.
Environmental factors also play a role in ammo performance. Cartridges exposed to moisture or extreme temperatures can malfunction. This can affect the primer or powder. This emphasizes the importance of proper ammunition storage, keeping rounds dry and within a moderate temperature range.
Over time, ammunition can degrade. The powder can lose its potency, and the primer may become less sensitive. Using old or degraded ammunition can lead to weak firing, FTFs, or even squib loads. Always check the manufacture date on your ammo and replace it if it’s beyond its shelf life.
Beyond the ammunition, the firearm itself is prone to problems. A dirty firearm is a common cause of jams. The buildup of powder residue, carbon, and other debris inside the action can impede the smooth cycling of the mechanism. Regular cleaning is, therefore, an essential practice for firearm maintenance and function.
Adequate lubrication is another critical factor. Without proper lubrication, the moving parts of the firearm will experience increased friction, leading to slower cycling and a greater chance of malfunctions. Over-lubrication, however, can also attract debris and lead to the same issues. The ideal level of lubrication is a thin, even coat applied to the specified points.
Worn or damaged components can also contribute significantly to gun jams. Springs that have lost their tension may not provide sufficient force for extraction or feeding. Extractors, the small hooks that pull the spent casing from the chamber, can break or wear down. The magazine is another component prone to issues, and a damaged magazine can result in feeding problems. It is essential to inspect all these components for wear and to replace any that are damaged.
Improper assembly, or the lack of assembly, is another potential cause of malfunction. If a firearm is not correctly assembled after cleaning or maintenance, it may malfunction. Parts might be installed incorrectly, or missing altogether. It is vital to carefully follow manufacturer instructions when disassembling and reassembling your firearm.
Operational Issues that Cause Gun Jams
Even if the firearm and ammunition are in perfect condition, operator error can still lead to malfunctions. It is essential that the user handles the firearm correctly.
An incorrect grip, commonly called “limp wristing”, can result in gun jams. In semi-automatic pistols, the slide needs a firm platform to cycle. If the shooter’s grip is not firm enough, the recoil energy is absorbed by the shooter’s wrist, reducing the momentum of the slide and potentially causing FTFs or FTEs. Maintaining a proper, firm grip is a critical aspect of shooting technique.
Loading and unloading procedures must be precise. Dropping a round into the chamber manually (as opposed to loading from the magazine) can cause a malfunction, especially if done carelessly. This can result in misfeeds or other types of jams. Always follow proper loading and unloading procedures as outlined in your firearm’s manual.
Interfering with the slide as it cycles can cause a problem. Some shooters might subconsciously try to slow the motion of the slide. Doing this can cause jams, especially FTFs. Allowing the slide to cycle freely ensures the cartridge is chambered correctly.
The magazine’s seating is also a vital step in avoiding a gun jam. Ensuring the magazine is fully seated within the firearm is essential for reliable feeding. If the magazine is not properly locked in place, it may not feed the rounds correctly, resulting in FTFs or even double feeds.
Environmental Challenges
The environment also plays a significant role in firearm function.
Extreme temperatures can impact the performance of both the firearm and ammunition. Cold temperatures can thicken lubricants and affect the burning characteristics of the powder, potentially leading to FTFs or reduced power. Heat, conversely, can cause excessive expansion of metal components and may accelerate the degradation of ammunition. Be aware of the temperature conditions when shooting, and take appropriate precautions.
Moisture is an enemy of firearms. Exposure to rain, humidity, or even condensation can cause rust and corrosion, which can quickly impair the function of the moving parts. Ensure your firearm is kept dry, and dry it after use.
Troubleshooting and Solving Gun Jams
Even with careful maintenance and shooting practice, jams can happen. Knowing how to safely clear a gun jam is a fundamental skill.
Above all, safety is paramount. The first step in dealing with any gun malfunction is to immediately point the firearm in a safe direction and keep it pointed downrange or in a safe direction where no accidental discharge will cause harm. Take a moment to assess the situation, ensuring your finger is off the trigger.
The next step is to identify the type of jam you are dealing with. Is it a FTF, FTE, or something else? Knowing the specific type of jam helps you to take the appropriate corrective action. This helps you identify the potential underlying causes.
The best approach varies depending on the type of jam. General recommendations include the tap, rack, and bang technique. Tap the bottom of the magazine to ensure it is fully seated. Rack the slide to eject the casing or chamber a new round. Attempt to fire the firearm again. If this does not fix the problem, and the issue is a double feed, a more involved procedure may be required, involving locking the slide back and removing the magazine. Always follow the manufacturer’s recommendations for clearing a jam, and if in doubt, seek assistance from a qualified gunsmith.
Preventative Actions
The best way to deal with a gun jam is to prevent it in the first place. By taking the proper steps, you can significantly reduce the chances of malfunctions.
A consistent cleaning and maintenance routine is critical for preventing jams. This includes regular disassembly, thorough cleaning, and lubrication, following the manufacturer’s recommendations. Clean your firearm after every shooting session, or at least after every period of significant use.
Ammunition storage is essential. Store your ammunition in a cool, dry place, away from direct sunlight and extreme temperatures. This helps ensure the cartridges maintain their reliability over time.
Using high-quality ammunition from reputable manufacturers is an easy way to limit jams. It is worth investing in quality rounds to avoid malfunction.
Practice proper shooting technique. A firm grip, correct stance, and consistent trigger pull are crucial for reliable firearm operation. Poor technique can cause malfunctions, especially in semi-automatic firearms.
The proper storage of your firearm is also important. Store your firearm in a secure location, away from moisture and extreme temperatures. This protects the firearm from corrosion and other environmental damage.
