The Smith & Wesson 637 Airweight, a popular concealed carry revolver, isn't without its potential issues. While many owners praise its lightweight design and reliability, understanding potential problems can help you make an informed decision and ensure the longevity of your firearm. This guide delves into common S&W 637 Airweight problems, offering solutions and preventative measures.
Common S&W 637 Airweight Issues
The 637's lightweight construction, while beneficial for concealed carry, contributes to some of its common problems. These often stem from the interaction between the alloy frame and the powerful .38 Special +P rounds it can fire.
1. Timing Issues
- Problem: One of the most frequently reported issues is timing problems. This can manifest as the cylinder not indexing correctly, leading to misfires or dangerous malfunctions. This is often due to wear and tear on the components, especially in guns that see heavy use.
- Causes: The lightweight alloy frame can flex under recoil from hotter .38 Special +P ammunition. This flexing can disrupt the timing mechanism, causing the cylinder to bind or misalign. Additionally, insufficient lubrication can exacerbate the problem.
- Solutions: Regular cleaning and lubrication are essential. Use a high-quality gun lubricant specifically designed for revolvers. If the problem persists, a qualified gunsmith may need to adjust the timing or replace worn parts. Consider using standard pressure .38 Special ammunition to reduce stress on the frame.
2. Recoil and Control
- Problem: The lightweight frame amplified recoil, making it difficult for some shooters to control, especially for those with less experience or smaller hands. This can result in flinching, poor accuracy, and even injury.
- Causes: The light weight of the gun simply means there's less mass to absorb the recoil energy. The use of +P ammunition further intensifies this effect.
- Solutions: Practice is crucial. Use proper shooting techniques, including a firm grip and proper stance. Consider using lighter ammunition (like .38 Special) for practice to improve your control. Using recoil reducing grips can help mitigate some of the sharp recoil.
3. Cylinder Locking Issues
- Problem: The cylinder locking mechanism can sometimes malfunction, resulting in the cylinder not locking firmly into place. This can lead to dangerous failures to fire or even accidental discharges.
- Causes: This can be due to wear and tear, dirt or debris, or damage to the locking mechanism itself.
- Solutions: Regular cleaning and lubrication are critical for preventing this issue. If the problem continues, a qualified gunsmith can inspect and repair the locking mechanism.
4. Finish Wear
- Problem: The finish of the Airweight is susceptible to wear, especially with frequent carrying and use. This is mostly a cosmetic issue, but can be a concern for some owners.
- Causes: Friction from carrying inside a holster, rubbing against clothing, and exposure to the elements all contribute to finish wear.
- Solutions: Proper holster selection is important. Choose a holster that fits snugly but doesn't excessively rub against the firearm's finish. Regular cleaning and applying a protective coating can help maintain the finish for longer.
5. Trigger Issues
- Problem: Some users report issues with the trigger, such as a heavy trigger pull or inconsistent trigger break.
- Causes: This could be due to the inherent design, wear, or debris interfering with the mechanism.
- Solutions: Regular cleaning and lubrication will help alleviate some issues. If the problems persist, a gunsmith can inspect and possibly adjust or replace components. Consider professional action work if you feel the trigger pull is unsafe or inconsistent.
Preventative Maintenance for Your S&W 637 Airweight
Regular maintenance is key to preventing problems and ensuring the reliable function of your 637 Airweight.
- Regular Cleaning: Clean your revolver after each range session, removing all debris and residue.
- Lubrication: Apply a high-quality gun lubricant to all moving parts, focusing on the cylinder and action.
- Proper Storage: Store your gun in a cool, dry place, away from excessive moisture and dust.
- Ammunition Selection: While the 637 can handle +P ammunition, consider using standard pressure .38 Special ammunition for practice to reduce wear and tear.
- Professional Inspection: Have your firearm inspected by a qualified gunsmith at least once a year for potential problems.
Conclusion: Responsible Ownership
The S&W 637 Airweight, despite its potential issues, remains a popular choice for concealed carry. Understanding the common problems, performing regular maintenance, and selecting the right ammunition will significantly contribute to its reliability and longevity. Responsible gun ownership involves proactive maintenance and awareness of potential problems to ensure safe and effective use. Remember to always practice safe gun handling techniques.
