Understanding the Sig P938 Legion and Its Potential Issues

The Sig P938 Legion is a single-action, all-metal pistol known for its accuracy and reliability. It’s a scaled-down version of the classic 1911 design, offering a familiar manual of arms for experienced shooters. However, its compact size and tight tolerances can also contribute to certain problems. These issues can range from failure to feed and eject to problems with the safety and trigger.

Common Categories of Sig P938 Legion Problems

• Failure to Feed (FTF): Rounds not chambering correctly.
• Failure to Eject (FTE): Spent casings not being ejected properly.
• Magazine Issues: Problems with magazine seating, feeding, or retention.
• Safety Problems: Issues with the manual safety engaging or disengaging.
• Trigger Problems: A gritty trigger pull, failure to reset, or dead trigger.
• Slide Lock Issues: Slide not locking back after the last round or locking back prematurely.

Detailed Analysis of Common Sig P938 Legion Problems

Let’s delve into each of these common problem areas with the Sig P938 Legion, providing potential causes and solutions.

Failure to Feed (FTF)

Failure to feed occurs when a round fails to chamber correctly. This can be a frustrating issue, but often has a simple solution.

Possible Causes:

• Magazine Issues: The magazine is the most common culprit. Weak magazine springs, damaged feed lips, or improper loading can all cause FTFs.
• Ammunition: Some P938 Legions can be picky with ammunition. Underpowered or out-of-spec ammunition can cause cycling problems.
• Extractor Problems: A worn or damaged extractor may not properly grip the cartridge rim, preventing it from being pulled from the magazine.
• Recoil Spring: A weak or worn recoil spring can cause short stroking, where the slide doesn’t travel far enough back to pick up the next round.
• Dirty Chamber/Ramp: A dirty or excessively carboned chamber or feed ramp can prevent the round from seating properly.
• “Limp Wristing”: Not holding the pistol firmly enough during firing can absorb too much recoil energy, leading to short stroking.

Troubleshooting Steps:

1. Try Different Magazines: If you have multiple magazines, try using a different one to see if the problem persists.
2. Try Different Ammunition: Switch to a different brand or type of ammunition, preferably one with a heavier bullet weight.
3. Clean and Lubricate: Thoroughly clean the chamber, feed ramp, and extractor. Use a high-quality gun lubricant on the slide rails and other moving parts.
4. Check the Extractor: Inspect the extractor for damage or wear. If necessary, replace it.
5. Replace the Recoil Spring: If the recoil spring is old or weak, replace it with a new one.
6. Firm Grip: Ensure a firm and consistent grip when firing the pistol.

Failure to Eject (FTE)

Failure to eject occurs when a spent casing is not properly ejected from the pistol after firing. This can result in a stovepipe malfunction, where the casing gets caught in the ejection port.

Possible Causes:

• Extractor Problems: As with FTFs, a worn or damaged extractor is a common cause of FTEs.
• Ejector Problems: A broken or damaged ejector can fail to properly kick the spent casing out of the ejection port.
• Ammunition: Underpowered ammunition can cause weak ejection.
• Dirty Chamber: A dirty chamber can cause the casing to stick, preventing proper ejection.
• Recoil Spring: A recoil spring that is too strong can cause the slide to return forward too quickly, not allowing enough time for the casing to eject.
• “Limp Wristing”: Same as with FTF, limp wristing can reduce the energy available for proper cycling.

Troubleshooting Steps:

1. Check the Extractor: Inspect the extractor for damage or wear. Replace if necessary.
2. Check the Ejector: Inspect the ejector for damage. Replace if necessary.
3. Try Different Ammunition: Switch to a different brand or type of ammunition, preferably one with a higher power factor.
4. Clean the Chamber: Thoroughly clean the chamber to remove any carbon buildup.
5. Recoil Spring: If the recoil spring is new, it may be too strong. Consider using a slightly weaker recoil spring.
6. Firm Grip: Maintain a firm and consistent grip when firing.

Magazine Issues

Magazine problems can manifest in various ways, from difficulty seating the magazine to rounds not feeding properly.

Possible Causes:

• Weak Magazine Spring: A weak spring can cause rounds to feed sluggishly.
• Damaged Feed Lips: Bent or damaged feed lips can prevent proper feeding.
• Dirty Magazine: Dirt and debris inside the magazine can interfere with the follower’s movement.
• Improper Loading: Overloading or improperly loading the magazine can cause feeding problems.
• Magazine Catch Problems: A worn or damaged magazine catch may not securely retain the magazine.

Troubleshooting Steps:

1. Replace Magazine Spring: Replace the magazine spring with a new, high-quality spring.
2. Inspect Feed Lips: Carefully inspect the feed lips for damage. If they are bent, try to gently bend them back into shape. If they are severely damaged, replace the magazine.
3. Clean the Magazine: Disassemble the magazine and thoroughly clean all parts.
4. Proper Loading: Ensure that the magazine is loaded correctly, with the rounds seated properly against the back of the magazine. Do not overload the magazine.
5. Check the Magazine Catch: Inspect the magazine catch for wear or damage. Replace if necessary.

Safety Problems

Issues with the manual safety can be a serious concern. The safety should engage and disengage smoothly and reliably.

Possible Causes:

• Dirt and Debris: Dirt and debris can accumulate around the safety mechanism, preventing it from functioning properly.
• Worn or Damaged Parts: Worn or damaged safety parts can cause the safety to be difficult to engage or disengage.
• Improper Installation: If the safety was not installed correctly, it may not function properly.

Troubleshooting Steps:

1. Clean the Safety Mechanism: Thoroughly clean the safety mechanism to remove any dirt or debris.
2. Inspect Safety Parts: Inspect the safety parts for wear or damage. Replace if necessary.

3. Inspect Trigger Parts: Inspect the trigger parts for wear or damage. Replace if necessary.
4. Professional Gunsmith: Trigger work on the P938 Legion is best left to a professional gunsmith, especially if you are experiencing a dead trigger or failure to reset.

Slide Lock Issues

Slide lock problems can include the slide not locking back after the last round or locking back prematurely.

Possible Causes:

• Magazine Follower: A worn or damaged magazine follower may not properly engage the slide stop.
• Slide Stop: A worn or damaged slide stop may not properly engage the magazine follower.
• Grip Interference: Your thumb or hand may be inadvertently pressing on the slide stop during firing.
