The .327 Federal Magnum is a .32-caliber revolver cartridge introduced in 2008, designed to deliver magnum performance with manageable recoil and an extra round of capacity compared with .38/.357 revolvers. It is used for defense and recreational revolver shooting.

The .327 Federal Magnum was introduced by Federal in 2008 as a high-performance .32-caliber revolver cartridge, the most powerful of a family of .32 revolver rounds. Its design goal was distinctive: deliver meaningful defensive performance while producing less recoil than the .357 Magnum, and — because the .32-caliber cartridges are slimmer — allow a revolver cylinder to hold an additional round compared with a comparable .38/.357 revolver. Ballistically the .327 Federal fires a .32-caliber bullet at high velocity for its bore, producing solid energy with recoil generally milder than the .357 Magnum. A practical feature mirrors the .38/.357 relationship: a revolver chambered for .327 Federal Magnum can also fire the milder, shorter .32-caliber cartridges in its family (such as .32 H&R Magnum and .32 S&W Long), giving owners lower-recoil, lower-cost practice options, with the barrel marking always the authority on what is rated to fire. It carved out a niche among shooters who want a defensive revolver cartridge with manageable recoil and the capacity advantage its slim diameter allows, particularly in compact carry revolvers. Its ammunition availability is steadier than many specialty rounds but narrower than the mainstream .38/.357. Today the .327 Federal Magnum is used for self-defense, concealed carry, home defense, and recreational revolver shooting, with steady availability. Its combination of magnum performance, manageable recoil, extra capacity, and family cross-compatibility is why it appeals to defensive revolver shooters.
