The Smith & Wesson Model 638, a lightweight, five-shot .38 Special revolver, has been a popular choice for concealed carry for decades. However, like any firearm, it's not without its potential issues. This guide will delve into common Smith & Wesson 638 problems, offering insights for both current owners and those considering purchasing one. Understanding these potential issues is crucial for ensuring safe and reliable operation.
Common Smith & Wesson 638 Problems:
This section outlines some of the most frequently reported problems associated with the Smith & Wesson Model 638. It's important to remember that not all 638s will experience these issues, and proper maintenance significantly mitigates the risk.
1. Timing Issues:
One of the most significant concerns with the 638 is potential timing problems. This can manifest as:
- Cylinder misalignment: The cylinder might not align correctly with the barrel, leading to misfires or dangerous malfunctions. This is often caused by wear and tear, particularly with extensive use.
- Clicking without firing: A common symptom of timing issues is the hammer falling without the cartridge firing. This usually points to a problem with the cylinder's alignment or the firing pin.
Solution: Timing issues require professional attention. A qualified gunsmith specializing in revolvers should inspect and adjust the timing to ensure safe and reliable function.
2. Recoil and Light Weight:
The 638's lightweight design, while beneficial for concealed carry, contributes to noticeable recoil. This can be uncomfortable for some shooters and even lead to issues over time:
- Increased felt recoil: The lightweight frame amplifies the recoil of the .38 Special cartridge, making it more difficult for some to control.
- Potential for damage: While less common, excessive recoil can contribute to wear and tear on the internal components of the firearm over time.
Solution: Practicing proper shooting techniques, using a recoil pad, and choosing appropriate ammunition can help mitigate recoil.
3. Light Strike Issues:
Another potential issue is a light strike, where the firing pin doesn't hit the primer with enough force to ignite the cartridge. This can be due to several factors:
- Weak firing pin spring: A weakened spring may not provide sufficient force for reliable ignition.
- Dirty firing pin: Accumulation of dirt and debris can impede the firing pin's function.
- Ammunition issues: In rare cases, the problem might stem from the ammunition itself.
Solution: A gunsmith can replace a weak firing pin spring. Regularly cleaning the firearm is crucial to prevent dirt buildup. Testing with different ammunition brands might help identify if the issue is related to the cartridges.
4. Wear and Tear:
Like any firearm, the 638 is subject to wear and tear over time. This is particularly true with heavy use and inadequate maintenance.
- Loose parts: Over time, screws and other components can loosen, impacting the firearm's accuracy and reliability.
- Surface wear: The finish can wear down, especially on areas that experience friction.
Solution: Regular cleaning and lubrication, as well as periodic inspection by a gunsmith are crucial to prevent excessive wear and tear.
Maintaining Your Smith & Wesson 638:
Proper maintenance is crucial to prevent many of the common problems associated with the 638. This includes:
- Regular cleaning: Clean the firearm after each use, removing all residue and debris.
- Lubrication: Apply gun oil to moving parts to prevent friction and wear.
- Periodic inspection: Regularly inspect for loose screws, wear and tear, and any signs of damage.
Conclusion:
The Smith & Wesson 638 is a capable firearm, but understanding its potential problems is vital for responsible ownership. Addressing issues proactively through proper maintenance and regular inspection can ensure its reliable function and longevity. Remember, when in doubt, consult a qualified gunsmith.
