At TASTYTSUNAMI, interest around the smith & wesson model 640, smith & wesson model 640 357 magnum, and smith & wesson model 640 review consistently comes from experienced carriers who want a revolver that disappears in a pocket yet stands up to years of hard use. The 640 answers that need without compromise.
The Enclosed Hammer Advantage
A defining trait of the Model 640 is its internal hammer (Centennial pattern). There is nothing to snag on clothing, holsters, or pockets during the draw.
Benefits:
- True snag-free presentation
- Double-action-only consistency
- Debris resistance in pocket carry
- Simplified manual of arms under stress
For many carriers comparing options, this single design choice is why the smith & wesson model 640 revolver is preferred over exposed-hammer J-frames.
Stainless Steel: Built for Carry, Built to Last
Unlike lightweight alloy J-frames, the 640 is solid stainless steel. That extra weight is intentional:
- Reduces felt recoil with .357 Magnum
- Increases durability for long service life
- Resists corrosion from sweat and humidity
- Adds shootability without sacrificing concealment
Shooters searching smith & wesson model 640 38 special often appreciate that this revolver can train comfortably with .38 Special while retaining the option of .357 Magnum performance.
Magnum Capability in a J-Frame
Not all J-frames are rated for .357 Magnum. The Model 640 is.
That means:
- Maximum defensive performance when desired
- Flexibility to run lighter .38 Special loads
- Confidence in strength and chamber support
- A revolver that grows with the shooter
This versatility is a common theme in any thorough smith & wesson model 640 review.
Trigger System: Consistency Over Complexity
As a double-action-only revolver, every trigger press is the same:
- Smooth, rolling pull
- Predictable break
- No transition between SA/DA modes
- Ideal for defensive repetition and training
This consistency is one of the most praised aspects of the smith & wesson model 640 pro and standard variants alike.
Fixed Sights, Fixed Confidence
The 640 uses a simple, durable fixed sight system:
- Serrated ramp front
- Integral rear channel in the top strap
- Zero risk of snagging or shifting
It’s built for defensive distances where speed and durability matter more than adjustment.

Why Many Carriers Prefer the 640 Over Lighter J-Frames
Ultra-light revolvers are easy to carry but harsh to shoot. The 640 strikes a balance:
- Heavy enough to tame recoil
- Light enough for pocket or waistband carry
- Durable enough for high round counts
- Comfortable enough for regular practice
This is why seasoned carriers often “graduate” to the smith & wesson model 640 357 magnum after trying lighter options.
Pocket, Waistband, and Holster Carry
The compact profile allows:
- Pocket holster carry
- Inside-the-waistband concealment
- Ankle carry
- Traditional belt holsters
Few magnum-capable revolvers offer this flexibility.

Many owners primarily train with .38 and carry .357.

The weight and trigger consistency play a big role here.
Durability and Longevity
