S&W 3566: An IPSC Game-Changer that Didn’t
The Smith & Wesson Model 3566, chambered in .356 TSW, was an innovative attempt to dominate IPSC's Limited Division by exploiting power factor rules. Developed from a lengthened 9x21mm case, it offered 15-round capacity and Major power factor potential. However, political maneuvering and rule changes mandating a .400-inch bullet diameter ultimately led to its downfall, making it a rare collector's item today.
