S&W 640 357 2.125″ FS 5-SHOT – STAINLESS STEEL RUBBER

Carrying a double-action-only J-frame in .357 Magnum means accepting a few trade-offs — and getting a lot in return. The S&W 640 in stainless with a 2.125-inch barrel is a dedicated concealment revolver with no exposed hammer to snag, chambered for serious defensive calibers. TacticCAL stocks it as a DOJ Roster listed handgun for CA buyers.

What Daily Carry with the 640 Actually Feels Like

The 640's concealed hammer is the defining feature for anyone who's drawn from a pocket holster or cover garment under pressure — there's nothing to catch. At 23 ounces with a stainless steel frame and cylinder, it's denser than an aluminum-frame J-frame, which some buyers prefer for reduced felt recoil when running .357 Magnum loads. The double-action-only trigger and fixed sights mean the manual of arms is simple: no decocker, no external safety to manage, just a consistent pull every time. Buyers who choose this over a semi-auto typically want the reliability profile of a revolver and the caliber flexibility of .357 Magnum/.38 Special in a micro-compact package. A Galco pocket holster or Safariland IWB option pairs naturally with this configuration. Full selection of California-compliant handgun catalog here.

Frequently asked questions

Is the 640 double-action-only, and what does that mean for the trigger compared to a standard J-frame?

Yes — the manufacturer specifies double-action-only with a concealed hammer. Every shot requires a full trigger pull through the same stroke. There's no single-action option. The trigger pull is longer and heavier than a standard DA/SA revolver, which is a deliberate design choice for snag-free carry.

Can I shoot .38 Special out of this 640, or is it .357 Magnum only?

The manufacturer description lists the caliber as .357 Magnum/.38 Special. Both cartridges are compatible. Many buyers train with .38 Special loads and carry .357 Magnum — a practical approach given the 640's 5-round cylinder capacity.

What should I take care of before I come in to start the DROS purchase?

You'll need a valid Firearm Safety Certificate in hand before the purchase transaction begins — the FSC is a prerequisite, not something completed afterward. Make sure it's current (valid 5 years) and bring a valid government-issued ID. You must be 21 or older to purchase a handgun in California.
