Smith & Wesson Model 640 — Stainless, Enclosed, Uncompromising

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

Smith & Wesson Model 640

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

.38 Special vs .357 Magnum in the 640

A major advantage is caliber flexibility.

.38 Special

Low recoil
Ideal for practice
Comfortable defensive option

.357 Magnum

Maximum stopping power
Greater penetration
Increased recoil but fully manageable in steel frame

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

Real-World Accuracy

Despite the short barrel, the Model 640 delivers practical defensive accuracy:

Fast sight acquisition
Tight groupings at 7–15 yards
Predictable point of impact
Excellent close-range control

The weight and trigger consistency play a big role here.

Durability and Longevity

The all-steel construction means:

High round count tolerance
Minimal wear from magnum loads
Long service life with proper care
Mechanical reliability in adverse conditions

This is not a revolver that wears out easily.
