Frequently Asked Questions

What was the Smith & Wesson Model 3566?

The Smith & Wesson Model 3566 was a competition pistol chambered in the proprietary .356 TSW cartridge. It was developed in the early 1990s specifically to compete in USPSA/IPSC Limited Division by achieving Major power factor with a 9mm-sized platform.

Why did the S&W 3566 fail in competition?

Despite meeting initial criteria, the S&W 3566 was ultimately disqualified from competition due to political maneuvering within USPSA. The organization later changed the rules, mandating a minimum bullet diameter of .400 inches for Major power factor, effectively ending the .356 TSW's viability.

What was the .356 TSW cartridge?

The .356 TSW (Team Smith & Wesson) was a cartridge developed by Smith & Wesson based on a lengthened 9x21mm case. Its goal was to achieve Major power factor ratings in practical shooting competitions while maintaining a 15-round capacity, offering an advantage over lower-capacity .45 ACP options.

Is the S&W 3566 a valuable collector's item?

Yes, the Smith & Wesson 3566 is considered a rare collector's item due to its unique history and limited production. Many examples are found with 9mm conversion barrels because the original .356 TSW ammunition is scarce and difficult to obtain.
