About
What it is, and why it matters
The Smith & Wesson Model 64 is a medium revolver built on Smith & Wesson's K-frame, introduced in 1970. Chambered in .38 Special with a 6-round cylinder. Constructed with a stainless steel frame and cylinder, this revolver offers excellent corrosion resistance and durability for years of reliable service. The 4.1-inch barrel provides an excellent balance of sight radius and portability, suitable for both duty carry and range work. The double-action/single-action trigger system allows both deliberate double-action shots and precise single-action fire when the hammer is manually cocked, providing versatility across different shooting scenarios. Weighing 975g (34.4 oz) empty, this revolver provides a solid, confidence-inspiring heft that helps absorb recoil without being overly burdensome for extended carry. Smith & Wesson has been producing K-frame revolvers for well over a century, continuously refining the platform with improved metallurgy, ergonomics, and manufacturing techniques while maintaining the fundamental reliability and accuracy that has made their double-action revolvers the benchmark against which all others are measured.
The K-frame platform has been in continuous production since 1899, making it one of the most refined and proven revolver designs in firearms history.
One of the most widely used police service revolvers. The stainless construction provides superior corrosion resistance.
