The Mossberg 500 is a legendary shotgun, prized for its reliability, versatility, and affordability. One popular modification among Mossberg 500 owners is the addition of a pistol grip. But what about the bolt? While the bolt itself isn't typically changed when adding a pistol grip, understanding its function and potential issues related to modifications is crucial for safe and reliable operation. This guide delves into the Mossberg 500 pistol grip and its relationship to the bolt, addressing common concerns and offering helpful insights.
Understanding the Mossberg 500 Bolt
Before discussing pistol grips, let's establish a foundational understanding of the Mossberg 500's bolt mechanism. The bolt is the heart of the shotgun's action, responsible for:
- Chambering a shell: The bolt strips a round from the magazine tube and feeds it into the chamber.
- Locking the action: Once a shell is chambered, the bolt locks securely, preventing accidental discharge.
- Ejecting spent shells: After firing, the bolt extracts and ejects the spent casing.
- Cocking the hammer: The bolt's movement typically cocks the hammer, preparing the firearm for the next shot.
The Mossberg 500 utilizes a relatively simple, robust pump-action mechanism, making it reliable even under harsh conditions. However, modifications, including the addition of a pistol grip, can indirectly affect its performance if not done correctly.
Pistol Grips and Their Impact
Adding a pistol grip to your Mossberg 500 primarily alters the ergonomics and handling characteristics of the shotgun. It provides a more compact and controllable platform, particularly beneficial in close-quarters situations or for individuals with smaller hands. However, it's important to note:
- No bolt modification is inherently required for a pistol grip installation. The pistol grip replaces the standard stock, but the bolt and its function remain unchanged.
- Improper installation: Improper installation of any modification, including a pistol grip, could potentially compromise the firearm's reliability or safety. Always follow manufacturer instructions or seek professional assistance if unsure.
- Legal Considerations: Laws regarding pistol-grip shotguns vary by location. Always check your local and state regulations before making any modifications.
Troubleshooting Potential Issues
While the pistol grip itself doesn't directly affect the bolt, some issues might arise indirectly:
- Malfunctions due to improper installation: If the receiver is not properly aligned after the pistol grip installation, it could lead to feeding or ejection problems. This is not a bolt issue, but rather an issue with the stock and its fit.
- Increased recoil: The shorter length of pull associated with a pistol grip might increase felt recoil. This isn't a bolt malfunction, but it is something to consider.
Maintaining Your Mossberg 500
Regardless of modifications, regular maintenance is key to ensuring your Mossberg 500 operates reliably. This includes:
- Cleaning: Regularly clean your shotgun after use, paying particular attention to the bolt and action.
- Lubrication: Use a suitable lubricant to keep moving parts smooth and prevent wear.
- Inspection: Periodically inspect your shotgun for any signs of wear or damage.
Conclusion
The Mossberg 500 pistol grip bolt relationship is primarily one of independence. The pistol grip installation doesn't require any changes to the bolt itself. However, proper installation and regular maintenance are crucial to ensuring the reliability and safety of your modified shotgun. Remember to always consult your owner's manual and adhere to all safety precautions. If you're unsure about any aspect of the modification process, seek assistance from a qualified gunsmith.
