The Sig Sauer P320 has become incredibly popular, and understanding its components is key to proper maintenance and operation. This guide focuses specifically on the Sig P320 slide stop, a crucial part responsible for locking the slide back after the last round is fired. We’ll explore its function, common issues, and how to troubleshoot them. We'll also delve into different slide stop options available for customization and enhancement.
Understanding the Sig P320 Slide Stop's Function
The slide stop lever, also known as the slide release, is a small but vital part of the P320's mechanism. Its primary function is to engage with the slide, holding it to the rear after the magazine is empty. This allows for easier reloading. When a fresh magazine is inserted, the slide stop can be released, allowing the slide to cycle forward and chamber a round.
How it Works: A Step-by-Step Look
- Empty Magazine: As the last round is fired, the slide's rearward movement is unimpeded.
- Slide Stop Engagement: The empty magazine follower engages with the slide stop lever, forcing it upwards and locking the slide in the rearward position.
- Manual Slide Release: The shooter can then manually depress the slide stop lever to release the slide.
- Reloading: The slide moves forward, chambering the first round from the newly inserted magazine.
Note: The slide stop also functions as a manual slide release. You can use it to lock the slide back even if the magazine is not empty, for example, for clearing malfunctions or conducting a weapons inspection.
Common Issues with the Sig P320 Slide Stop
While generally reliable, the P320 slide stop can occasionally present issues. These often stem from wear and tear, improper cleaning, or even manufacturing inconsistencies.
1. Slide Stop Failure to Lock Back
This is a common problem. Several factors can cause this:
- Worn Slide Stop: Over time, the slide stop can wear down, losing its ability to reliably engage with the slide.
- Dirty Slide Stop: Buildup of debris can interfere with the smooth functioning of the slide stop mechanism.
- Damaged Slide Stop: A damaged slide stop, perhaps due to a drop or impact, will likely fail to function correctly.
- Magazine Issues: Occasionally, a faulty magazine follower may prevent proper engagement with the slide stop.
2. Slide Stop Sticking or Binding
A sticking slide stop can prevent smooth operation. This usually points to:
- Lubrication Issues: Either too little or too much lubrication can hinder the slide stop's movement.
- Debris Buildup: Similar to failure to lock back, grime can impede its free movement.
- Bent or Damaged Lever: A bent or damaged slide stop lever will bind and not move freely.
Troubleshooting Your Sig P320 Slide Stop
Addressing slide stop problems usually involves these steps:
- Cleaning: Thoroughly clean the slide stop and its engagement points with a suitable cleaning solvent and brush.
- Inspection: Carefully examine the slide stop for any damage, bending, or wear.
- Lubrication: Apply a thin layer of high-quality gun lubricant to the slide stop and its interaction points. Avoid excessive lubrication.
- Magazine Check: Ensure that your magazine is functioning correctly; replace it if necessary.
- Replacement: If cleaning and inspection reveal damage or wear, replace the slide stop with a new one.
Upgrading Your Sig P320 Slide Stop: Customization Options
Many aftermarket companies offer enhanced Sig P320 slide stops. These often feature:
- Extended Levers: Easier to manipulate for shooters with larger hands.
- Ambidextrous Levers: Allowing for easy operation from either side of the firearm.
- Different Materials: Some are constructed from materials like stainless steel or aluminum for increased durability or aesthetics.
| Feature | Stock Slide Stop | Aftermarket Options |
|---|---|---|
| Material | Typically Steel | Steel, Aluminum, Polymer |
| Length | Standard | Extended, Ambidextrous |
| Finish | Varies | Various finishes (e.g., Cerakote, Black Nitride) |
