Guns & Ammo's Eric Poole and Patrick Sweeney are joined by Federal Premium's Christopher Laack to discuss the .32 Harrington & Richardson (H&R) Magnum and the .327 Federal Magnum. Sweeney tested and compared modern loads for these cartridges in Ruger and Smith & Wesson revolvers in "More Than Retro," an exclusive feature in the October 2025 issue of Guns & Ammo. These .32s are enjoying a resurgence in the concealed carry revolver segment with introductions in 2025, including S&W's Model 642 "The Ultimate Carry Revolver." Laack discusses the engineering that led to the .327 Federal introduction to advance bullet performance and increase capacity potential in small-frame revolvers, while Sweeney recounts his experience and test results.
The .32s are based on a .312-diameter bullet. When compared to .32 S&W and .32 S&W Long, the .32 H&R was considered a "magnum" when introduced in 1984, but the .327 Federal was a leap forward when it was introduced with modern bullets in 2008 for the Ruger SP101 and LCR. A joint venture between Federal Premium and Sturm, Ruger, & Co., Guns & Ammo re-evaluated the .327 Federal with the original SP101 prototype in .32 H&R Mag., which was re-chambered and marked ".327" over the ".32 H&R" stamping. With the new Federal Hyra-Shok Deep, engineers have renewed the .32 H&R Magnum's credentials as a viable self-defense cartridge for the modern era. Learn more about the development, details, and ballistic potential of each cartridge in this episode of Guns & Ammo's "The Buzz Podcast."

Are You A Charlotte?
In 1997, actress Kristin Davis’ life was forever changed when she took on the role of Charlotte York in Sex and the City. As we watched Carrie, Samantha, Miranda and Charlotte navigate relationships in NYC, the show helped push once unacceptable conversation topics out of the shadows and altered the narrative around women and sex. We all saw ourselves in them as they searched for fulfillment in life, sex and friendships. Now, Kristin Davis wants to connect with you, the fans, and share untold stories and all the behind the scenes. Together, with Kristin and special guests, what will begin with Sex and the City will evolve into talks about themes that are still so relevant today. "Are you a Charlotte?" is much more than just rewatching this beloved show, it brings the past and the present together as we talk with heart, humor and of course some optimism.
