Overview and Key Specifications

This compact DAO revolver chambers .357 Magnum and .38 Special +P, offering a 5-round capacity with a 2.125″ barrel and overall length of 6.625″. It weighs 22.4 oz, features black synthetic textured grips for a secure hold, and a stainless finish for corrosion resistance. The enclosed hammer and snag-free profile make it optimized for concealed carry while maintaining the ability to deliver full-power .357 rounds when needed.

Features That Matter in the Field

The dovetail tritium night sight is a standout for low-light readiness—providing fast sight acquisition without adding bulk. Cylinder cuts for moon clips allow for faster reloads and straightforward use with rimless defensive loads. The double-action-only trigger offers a consistent pull that many defensive shooters prefer for holster draws and close-quarters engagements.

At a price of $899.99, the 640 Pro Performance bridges standard production reliability and Performance Center enhancements, delivering competition-level specifications with factory reliability. Whether you want a stout backup or a primary deep-concealment option, this revolver answers the demand for a small package with large-caliber capability. View product details and pricing.
