Top 5 SIG P365 Problems Every Owner Should Know

The Sig P365 is a popular choice for people who want a small, easy-to-carry handgun. Many like it for its size, comfort, and high capacity. It has become a favorite for concealed carry and everyday use.

Knowing the most common Sig P365 problems helps owners make informed choices and stay safe at the range or while carrying. This article takes a closer look at the top 5 issues users have reported, giving readers a clear overview before they buy or use the pistol.

1) Broken MIM firing pins causing failures

One of the most common complaints about the Sig P365 is the issue with its MIM (metal injection molded) firing pins breaking. Several owners have reported that the firing pin can snap, leading to light strikes or even total failure to fire.

This problem often happens because of primer drag. Primer drag occurs when the firing pin stays in contact with the primer as the slide moves back, putting extra stress on the pin. Early P365 models appear to be more affected by this issue.

Some users on forums say dry firing the pistol too often may also increase the risk of a broken firing pin. Striker channel dirt or weak springs can make the problem worse. These factors may keep the firing pin from moving correctly.

SIG Sauer has made changes over time to address these problems. Newer models use improved parts, but reports of broken MIM firing pins still occasionally occur. 

2) Striker drag leading to premature striker breakage

Striker drag on the SIG P365 can be seen as a mark left on the primer after firing. This occurs when the striker is still in contact with the primer as the barrel unlocks and slides backward. Striker drag is a common topic among P365 owners.

Some early P365 models had issues with striker breakage. This was mainly caused by the striker tip being weakened over time from the repeated stress of dragging across the primer. In some cases, the striker could even fracture.

Newer P365 models have addressed this by reinforcing the striker design. The problem of breakage related to striker drag was largely linked to initial factory parts and has been corrected in updated versions. However, minor striker drag can still be seen in many pistols and is usually not a major concern for most shooters.

For those interested in more community discussion, users have shared personal experiences with striker drag and breakage on owner forums. Some also report that striker drag appears in other handgun brands, but early P365 batches were more strongly affected.

3) Cosmetic trigger scratches on new units

Some owners of the Sig P365 notice scratches near the magazine or grip area, sometimes even on brand new pistols. These are often light marks that look like they happened during assembly or while parts were fitted together at the factory.

In many cases, these scratches come from contact with the trigger spring or magazine when the gun is being used or tested at the factory. A discussion on Sig Talk explains that the trigger spring sometimes rubs against the magazine, causing small scratches. This happens because the spring is made to be long enough to stay secure.

Small cosmetic scratches do not cause any major problems for the gun’s function. The marks may not look good, but they are mostly just part of normal wear and tear seen on many new P365 pistols. Some users notice these more if they inspect their new gun closely, but they do not mean the pistol has been used or is defective.

For most people, these scratches are only a cosmetic issue and do not affect performance or safety.

4) Night sights breaking off easily

Many Sig P365 owners have noticed problems with their night sights breaking or falling off more easily than expected. In some cases, the front night sight has become dead or even gone missing after only a few weeks of use. This issue can be frustrating for people who rely on their sights for accuracy, especially in low-light conditions.

Some reports mention the green ring on the front sight remains, but the tritium insert is either dead or has fallen out. A few users have also cracked their sights during accidental drops or impacts, such as falling while holding the gun or during cleaning. When the sights are damaged, they may no longer glow, which affects their usefulness.

It is important to keep the P365 away from hard impacts, as the night sights are more delicate than some realize. Replacing broken sights with higher quality or more durable options can help avoid these issues. Owners should also inspect their sights regularly to spot any signs of damage or loosening before it becomes a problem.

5) Issues with failure to go fully into battery

Some owners have noticed that the SIG P365 does not always return fully to battery. This means the slide does not move all the way forward after firing or chambering a round. When this happens, the pistol cannot fire until the slide is pushed all the way into place.

One common reason for this problem is a dirty or dry firearm. Buildup of carbon, dust, or old lubricant can slow down the slide. Cleaning the gun and using quality lubricant can often improve performance.

A weak recoil spring or worn parts might also cause the slide to get stuck. In some cases, changing to a stronger recoil spring has helped reduce failures to return to battery, as discussed by users on SIGforum.

Rounds with rough edges, dents, or defects can sometimes make it hard for the slide to close. Using factory ammo and inspecting rounds before loading can help avoid this issue.

Some users report that failures happen more in new guns before they are fully broken in. After more rounds are fired, the gun’s parts can move more smoothly, leading to fewer issues with returning to battery.

Understanding the SIG P365 Platform

The SIG P365 has become known for its high capacity and compact build in the concealed carry market. Many gun owners choose this model due to its size, performance, and wide variety of features.

Design and Features Overview

The SIG P365 was first introduced in 2018 as a micro-compact pistol for concealed carry. It features a 10- or 12-round magazine in a very slim, short frame that makes it easy to hide. The pistol uses a striker-fired action and comes with a nitron-coated stainless steel slide.

SIG Sauer designed the P365 with a clean, textured grip, high visibility X-Ray3 night sights, and a crisp trigger. The slide and frame allow for a low bore axis, which helps reduce muzzle flip and makes follow-up shots easier. Users can find models with different slide lengths, optics-ready designs, or special finishes.

The controls are simple and easy to reach, making it friendly for both beginners and experienced shooters. Its reliability is a key reason for its popularity, but some early models had issues with parts like the striker. Many updates have since addressed these areas.

Comparison with Similar Concealed Carry Pistols

Compared to other concealed carry options like the Glock 43X, Springfield Hellcat, and Smith & Wesson Shield Plus, the P365 stands out for its capacity and small size. While the Glock 43X holds 10 rounds, the SIG P365 can offer the same or more magazine capacity in a noticeably shorter grip frame.

The P365’s weight is also lower than some competitors, often weighing about 17 to 18 ounces unloaded. Its sights are metal and bright, making them better than the basic polymer sights often found on other pistols in this class.

Addressing Common Maintenance and Reliability Concerns

Regular upkeep keeps the SIG P365 working as intended. Good maintenance lowers the chance of part failures and helps avoid the most frequent problems reported by owners.

Recommended Cleaning and Lubrication Practices

Keeping the SIG P365 clean is key for smooth operation. After every range session, owners should field strip the gun and clean the barrel, slide, and frame rails. Use a nylon brush to remove carbon and dirt. Pay close attention to the extractor and feed ramp, as buildup in these spots often causes feeding or extraction issues.

Lightly oil contact points such as the slide rails, barrel lugs, and trigger parts. Don’t over-lubricate, as too much oil can attract dust and lint. The manual lists factory-recommended lubrication points. Cleaning supplies designed for pistols, like CLP (Cleaner, Lubricant, Protectant), work best. Routine cleaning helps prevent common malfunctions like failure to extract or slide lock issues, which are among the most frequent SIG P365 problems.

Tips for Enhancing Long-Term Durability

To extend the lifespan of the SIG P365, inspect springs and small parts for wear regularly. Pay special attention to the recoil spring and striker assembly; both can show signs of fatigue after heavy use or many rounds. Replace them as needed—SIG recommends a new recoil spring assembly every 2,500–3,000 rounds.

Use quality factory ammunition to prevent stoppages. Dry-fire practice should only be done with a snap cap to avoid possible firing pin damage. Store the pistol in a dry, cool place to avoid rust, and use a dedicated case to keep out dust or debris. Adopting these habits helps reduce issues like broken firing pins and spring fatigue over time.
