The SP101 in .327 Federal Magnum fits 6 rounds in the cylinder due to the smaller cartridge diameter versus .357 Magnum's 5 rounds. This gives a meaningful capacity upgrade in a compact carry revolver while retaining the ability to chamber .32 H&R Magnum and .32 S&W Long — a significant versatility advantage. The 3.06-inch barrel is the primary configuration.
