S&W PC Model 640 Black Edition .357 Mag, 5-Round
Pros & cons
What works
- 23 oz weight -- over 4 oz lighter than a steel-frame Ruger SP101 in .357 Mag
- Tritium night sights provide 15-year illumination without batteries
- Cylinder cut for full-moon clips enables 2-second reloads versus 4+ seconds loading individual rounds
- Cerakote finish increases corrosion resistance by over 10x compared to standard bluing
Trade-offs
- No external hammer -- cannot be fired single-action, limiting precision shot potential
- Five-round capacity is standard but 1-2 rounds less than some modern micro-compact 9mm pistols
- Aggressive checkering on the boot grip can be uncomfortable against bare skin during all-day carry

About this product
The Ironclad Armory S&W PC Model 640 Black Edition .357 Mag is a double-action-only J-frame revolver specifically engineered for discreet, all-weather carry. This 5-round Performance Center build delivers .357 Magnum authority in a stainless steel frame weighing 23 ounces. Its Cerakote finish and tritium night sights make it a purpose-built tool for shooters who prioritize reliability over round count.
What is the Ironclad Armory S&W PC Model 640 used for?
This revolver is used for concealed carry in demanding environments where corrosion resistance and low-light readiness are non-negotiable. The double-action-only trigger, with an internally polished reset, provides a consistent pull every time. Its compact J-frame dimensions make it suitable for ankle or deep inside-the-waistband carry.
How does the Ironclad Armory S&W PC Model 640 compare to the Taurus 856 Executive Grade?
The Smith & Wesson Performance Center build is better at achieving mechanical precision and durability, justifying its roughly $300 premium. The Taurus 856 offers a 6-round capacity versus the S&W's 5 rounds. However, the 640's cylinder cut for full-moon clips facilitates faster, more positive reloads, and its stainless steel construction under the Cerakote outlasts the Taurus's aluminum alloy frame in high-round-count scenarios. For a dedicated hunter who also needs a defensive sidearm, the Stevens 334 in .243 Win might serve as a more capable primary.
What does it weigh and what are the dimensions?
The revolver weighs 23 ounces (652 grams), with an overall length of 7.25 inches and a height of 4.75 inches. The fluted barrel contributes to this weight distribution, shaving approximately one ounce from the front end compared to a solid barrel. This brings the balance point back toward the shooter's hand, aiding in recoil management.
Who is this NOT for?
This revolver is not for shooters seeking a high-capacity, striker-fired pistol for competition. The 5-round capacity is a functional limit of the J-frame design. It's also not an ideal choice for a novice's first handgun due to the snappy recoil of full-power .357 Magnum loads. A new shooter would be better served by a full-size 9mm or a low-recoil platform like a Stevens 555 Compact in 20 Gauge.
What's in the box?
You receive the pistol, one full-moon clip, a factory cable lock, and the standard Smith & Wesson hard case. Ironclad Armory includes a 32-page armorer's supplement detailing the Cerakote curing process and Performance Center action work tolerances. The package ships with an ATF Form 4473 compliance checklist to streamline your FFL transfer.
Is the Ironclad Armory S&W PC Model 640 worth it at $951.99?
At $951.99, it's worth it for the professional who needs the specific combination of a stainless J-frame, corrosion-resistant finish, and factory-installed tritium sights. You're paying for a Performance Center-tuned action that eliminates the 12-14 pound grit present in many stock double-action revolvers. The upfront cost is offset by the durability; this finish will last over 5,000 draw cycles from a Kydex holster without significant wear.

Frequently asked questions
- Is it compatible with .38 Special ammo?
- Yes. It is fully compatible with all .38 Special ammunition, including +P and +P+ variants designed for short barrels. The cylinder geometry is optimized for .357 Magnum, but the .38 Special casings headspace perfectly. You can expect velocities approximately 50-75 fps slower from this 2.5-inch barrel compared to a 4-inch service revolver.
- Does it fit standard J-frame holsters?
- Yes, with one caveat. The external dimensions match a standard J-frame, but the thicker front sight blade on the tritium night sight may not clear some tightly molded kydex holsters designed for the traditional ramp sight. We recommend using an open-top, sight-channel holster from brands like Vedder or Tulster for reliable clearance.
- How long does shipping take?
- Shipping to your chosen FFL dealer takes 3-5 business days from order verification. The process includes a mandatory 24-hour compliance verification to ensure all state and local regulations are met. Orders placed before 2 PM Mountain Time typically ship the same business day via FedEx 2Day.
- Can I return it if it doesn't fit my hand?
- No. Due to federal firearms regulations, all firearm transfers to an FFL are final sales. We strongly recommend handling a J-frame revolver at a local range before purchase. If there is a mechanical defect covered under warranty, Smith & Wesson’s Performance Center warranty process is handled directly through their service arm, not via Ironclad Armory returns.
- Does this work with a Crimson Trace Laser Grip?
- Yes. The frame geometry accepts all standard J-frame round-butt grips. Crimson Trace’s LG-105 LaserGrip is a direct-fit model for this revolver. The activation switch is positioned to engage naturally during a high-hand, thumbs-forward grip without altering your draw stroke.
- Is the Cerakote finish durable?
- Yes. The Cerakote H-190Q finish applied has a pencil hardness rating of 9H and a salt spray resistance rating exceeding 1,000 hours. It is more resistant to abrasion and chemical solvents than traditional bluing. Holster wear will manifest as a polished sheen on high-contact edges, not as chipping or flaking.
