For carriers who prioritize concealability without sacrificing terminal performance, a compact J-frame revolver remains an excellent option. Tight, reliable ergonomics, simple controls, and robust construction make small revolvers a go-to for everyday carry and backup roles.

SMITH & WESSON 640 PRO PERFORMANCE delivers a Pro Series twist on a classic J-frame design: a double-action-only (DAO) small-frame revolver chambered for .357 Magnum and .38 Special +P with a 5-round cylinder capacity. The frame, barrel, and cylinder are stainless steel for durability, while the black synthetic textured grip keeps the package light and controllable. Shop this product

Build and handling

The 640 Pro Performance balances size and capability. With a 2.125″ barrel, overall length of 6.625″, and a weight of 22.4 oz, it’s short enough for concealment yet heavy enough to help manage recoil from .357 loads. The enclosed hammer offers a snag-free profile for draws from a pocket or holster, and the cylinder is cut for moon clips to facilitate speedier reloads under stress.

Sights and ergonomics

Dovetail-mounted tritium night sights provide low-light aiming capability without adding bulk, while the textured synthetic grip improves control during follow-up shots. Construction materials combine aluminum alloy and steel components to balance strength and weight, aligning with practical carry demands.

Caliber, capacity, and real-world use

Chambered for .357 Magnum with the ability to run .38 Special +P, this revolver offers flexibility: .38 Special rounds provide softer recoil for practice or defensive carry, while .357 Magnum delivers higher energy for maximum stopping potential in critical scenarios. The 5-round capacity is standard for J-frames; moon-clip compatibility offsets reload speed limitations compared to semi-autos.

Buying considerations

The Pro Performance line bridges production reliability and competition-grade features, and the 640 Pro Performance reflects that: enhanced specs without sacrificing the serviceable platform. At a retail price of $899.99, buyers get stainless construction, DAO operation, night sights, moon-clip capability, and a durable synthetic grip—features valuable for CCW-minded shooters.
