Troubleshooting Stevens 311A 12 Gauge Misfires: A Comprehensive Guide
The Stevens 311A 12 gauge shotgun, a classic side-by-side firearm, is known for its reliability and simplicity. However, like any mechanical device, it can experience issues, with misfires being a common concern. Understanding the potential causes of these misfires and how to address them is crucial for any owner. This guide provides a comprehensive overview of troubleshooting Stevens 311A 12 gauge misfires, offering practical solutions to get your shotgun back in working order. We’ll explore common problems, delve into detailed inspection procedures, and offer preventative maintenance tips.
Understanding the Basics of Misfires
A misfire occurs when the firing pin strikes the primer of a shotshell, but the shotshell fails to ignite. This can be a frustrating and potentially dangerous situation. It’s essential to distinguish a misfire from a hangfire, which is a delayed ignition. Always treat a misfire with extreme caution, keeping the muzzle pointed in a safe direction for at least 30 seconds before carefully unloading the firearm.
Common Causes of Stevens 311A Misfires
Several factors can contribute to Stevens 311A 12 gauge misfires. These include:
- Faulty Ammunition: This is often the most common culprit. Damaged, old, or improperly stored shotshells can have compromised primers that fail to ignite reliably.
- Weak or Broken Firing Pin: The firing pin’s impact is crucial for igniting the primer. A worn, bent, or broken firing pin may not deliver sufficient force.
- Dirty or Obstructed Firing Pin Channel: Debris, grime, or old lubricant can impede the firing pin’s movement, reducing its striking power.
- Weak Hammer Springs: The hammer spring provides the power behind the hammer’s strike, which in turn drives the firing pin. A weak spring can result in insufficient force.
- Headspace Issues: Excessive headspace (the distance between the breech face and the cartridge head) can prevent the firing pin from reaching the primer with sufficient force.
- Damaged or Worn Breech Face: Damage to the breech face can interfere with proper cartridge seating, leading to misfires.
Troubleshooting Steps for Stevens 311A Misfires
Before attempting any troubleshooting, ensure the firearm is unloaded and safe. Always wear eye protection during inspection and repair procedures.
Step 1: Inspect the Ammunition
The first step is to rule out faulty ammunition. Examine the shotshells for any signs of damage, corrosion, or deformation. Try a different brand or batch of ammunition known to be reliable. If the misfires cease with different ammunition, the original ammunition was likely the problem.
Step 2: Examine the Firing Pins
The Stevens 311A has two firing pins, one for each barrel. Carefully inspect both firing pins for any signs of damage, such as bending, breakage, or excessive wear. To access the firing pins, you’ll typically need to remove the stock and the lock plate. Consult a gunsmithing manual or online resources for specific disassembly instructions. Ensure you are comfortable with these procedures or seek professional assistance.
Once accessible, check the firing pin protrusion. The firing pin should extend a certain distance beyond the breech face when fully forward. If the protrusion is insufficient, the firing pin may not be striking the primer with enough force.
Step 3: Clean the Firing Pin Channels
A dirty or obstructed firing pin channel can significantly impede the firing pin’s movement. Use a solvent designed for firearms cleaning to thoroughly clean the firing pin channels. A small brush or pipe cleaner can help remove stubborn debris. Ensure the channels are completely dry before reassembling.
Step 4: Check the Hammer Springs
Weak hammer springs can reduce the force behind the hammer’s strike. Unfortunately, assessing the strength of the hammer springs directly can be difficult without specialized tools. However, you can visually inspect the springs for any signs of damage or corrosion. If the springs appear weak or compressed, consider replacing them.

Step 5: Inspect the Breech Face
Examine the breech face for any signs of damage, such as pitting, erosion, or excessive wear. Damage to the breech face can prevent proper cartridge seating, leading to misfires. If the breech face is significantly damaged, it may require professional repair or replacement.
Step 6: Headspace Check (Requires Professional Assistance)
Checking headspace requires specialized gauges and expertise. If you suspect a headspace issue, it’s best to consult a qualified gunsmith. Attempting to adjust headspace without the proper tools and knowledge can be dangerous and may damage the firearm.
Preventative Maintenance to Minimize Misfires
Regular maintenance is crucial for preventing Stevens 311A 12 gauge misfires and ensuring the longevity of your shotgun. Here are some essential preventative maintenance tips:
- Clean Regularly: Clean your shotgun after each use to remove powder residue, dirt, and grime. Pay particular attention to the firing pin channels and breech face.
- Lubricate Properly: Use a high-quality gun lubricant to keep the moving parts of your shotgun operating smoothly. Avoid over-lubrication, as excess lubricant can attract dirt and debris.
- Store Ammunition Properly: Store your ammunition in a cool, dry place to prevent deterioration. Avoid storing ammunition in humid or extreme temperature conditions.
- Inspect Regularly: Periodically inspect your shotgun for any signs of wear, damage, or corrosion. Address any issues promptly to prevent them from escalating.
- Professional Inspection: Consider having your shotgun professionally inspected by a qualified gunsmith every few years. A gunsmith can identify potential problems that you may not be able to detect yourself.
When to Seek Professional Help
If you’ve tried the troubleshooting steps outlined above and are still experiencing Stevens 311A 12 gauge misfires, it’s time to seek professional help. A qualified gunsmith has the expertise, tools, and knowledge to diagnose and repair complex firearm issues. Do not attempt repairs beyond your skill level, as this can be dangerous and may further damage the firearm. [See also: Finding a Qualified Gunsmith Near You]
