The 1911 pistol, a legendary firearm, relies on a complex interplay of parts for safe and reliable operation. Among these crucial components is the firing pin stop, a seemingly small piece with a significant impact on the gun's functionality and safety. This article provides a comprehensive guide to the 1911 firing pin stop, covering its function, common problems, troubleshooting, and solutions. Understanding the firing pin stop is vital for responsible 1911 ownership.
Understanding the Role of the 1911 Firing Pin Stop
The firing pin stop, as its name suggests, prevents the firing pin from moving forward unless the trigger is pulled and the sear is disengaged. It's a small, often overlooked part, but its failure can lead to catastrophic consequences, including accidental discharge. Its primary functions are:
- Preventing Accidental Discharge: The firing pin stop's most crucial role is to physically block the firing pin from striking the primer unless the trigger is fully depressed. This prevents the gun from going off unintentionally.
- Retaining the Firing Pin: The firing pin stop also helps secure the firing pin in place, preventing it from becoming dislodged during operation. Loss of the firing pin can render the weapon inoperable or cause malfunctions.
- Contributing to Smooth Cycling: Although not its primary function, the proper functioning of the firing pin stop contributes to the overall smooth cycling of the 1911 action. A malfunctioning stop can interfere with this process.
How the Firing Pin Stop Works
The firing pin stop interacts with several other parts of the 1911. When the trigger is pulled, the sear releases the hammer, which then strikes the firing pin. Simultaneously, the firing pin stop is pushed back slightly, allowing the firing pin to move forward and strike the primer. Once the shot is fired, the stop returns to its original position, blocking the firing pin. This precise sequence is essential for safe and reliable operation.
Common Problems with the 1911 Firing Pin Stop
While generally robust, the firing pin stop can experience issues. These often stem from wear and tear, improper installation, or using parts that are not correctly fitted.
- Broken Firing Pin Stop: A broken firing pin stop is a serious safety hazard. It can fail to restrain the firing pin, leading to an accidental discharge.
- Loose Firing Pin Stop: A loose firing pin stop can cause the firing pin to move slightly, leading to light primer strikes or failure to fire. This can make the weapon unreliable.
- Incorrect Installation: Incorrect installation can lead to similar problems as a loose stop, or prevent the gun from functioning properly altogether.
- Wear and Tear: Over time, the firing pin stop, like other parts of the 1911, can wear down, leading to the above mentioned issues.
Diagnosing Firing Pin Stop Problems
Troubleshooting a malfunctioning 1911 involves careful inspection and testing. If you suspect a problem with the firing pin stop, do not attempt to field strip or repair the firearm yourself unless you have adequate experience and training. A professional gunsmith should handle any repairs or modifications. Look for:
- Visual Inspection: Carefully inspect the firing pin stop for any signs of damage, such as cracks, bends, or excessive wear.
- Function Test: Have a qualified professional function test the firearm to determine if the firing pin stop is functioning correctly. This is not something to be done at home without proper safety equipment and training.
Repairing or Replacing a 1911 Firing Pin Stop
Replacing a damaged or worn firing pin stop is usually a straightforward process for a skilled gunsmith. However, attempting repairs without the necessary expertise can be dangerous and should be avoided.
The steps generally include:
- Disassembly: Carefully disassemble the firearm to access the firing pin stop. This process is intricate and should be done by experienced individuals only.
- Removal: The old firing pin stop is removed and replaced with a new, correctly fitted part.
- Reassembly: The firearm is reassembled, ensuring all parts are correctly seated.
- Function Check: A thorough function test by a qualified professional is essential to verify that the new firing pin stop is functioning correctly and safely.
Choosing a Replacement Firing Pin Stop
When replacing a firing pin stop, it's crucial to use a high-quality part from a reputable manufacturer. Using a substandard part can lead to malfunctions or safety issues. Look for parts made of durable materials, such as hardened steel. Always ensure the replacement part is compatible with your specific 1911 model.
Case Study: A 1911 Misfire Due to a Worn Firing Pin Stop
A local gunsmith reported a case of a 1911 experiencing frequent light primer strikes. Upon inspection, he found the firing pin stop was significantly worn, preventing proper engagement with the firing pin. Replacing the stop immediately resolved the issue, restoring the firearm's reliability. This emphasizes the importance of regular maintenance and inspection of all firearm components.
