Ruger Reintroduces the SP101 Revolver in .327 Federal Magnum

.327 Federal Magnum revolver by Ruger with stainless barrel and black rubber grips with a wood insert

Originally introduced in 2007 and later discontinued, Ruger is pleased to announce the return of the SP101 revolver chambered in .327 Federal Magnum. Ruger’s newest revolver has been updated and improved over the first model SP101 .327 Federal Magnum to optimize the full performance of the .327 round. With its 4.2-inch barrel, the SP101 fully maximizes the full velocity potential of the .327 Federal Magnum with some loads reaching up to 1,500 feet-per-second.

Eight years ago, Ruger, in collaboration with Federal Cartridge Company, developed the .327 Federal Magnum cartridge in order to fit one more round in a small-framed revolver’s cylinder and offering the performance velocity of a .357 Magnum without the recoil and muzzle blast. Based on the .32-caliber bullet, but loaded to higher pressures, the .327 Federal Magnum performs better than the .38 Special, .357 Magnum or 9mm. Upon the .327 Federal Magnum’s introduction, Federal’s lead design engineer Larry Head said, “The .327 Federal Magnum is ideal for personal defense and has the potential for future application in field use. Using a slightly longer .32 H&R Magnum case and our advanced powder and bullet technology, we’re able to offer more performance out of a smaller platform. And its recoil is milder than the .357 Magnum.” In 2009, the cartridge won the NRA’s Golden Bullseye Award for Ammo of the Year.

Few companies chambered revolvers for the cartridge, but all were to be discontinued by 2013, including Ruger’s own SP101 with a 3 1/16-inch barrel. That’s not to say, however, that the round was a dud. It has always had its fair share of fans.

The new Ruger SP101 in .327 Federal Magnum is a double/single-action revolver with a six-round cylinder built on a stainless steel frame. It has a light-gathering green fiber optic front sight and an adjustable rear sight. The rubber grip has checkered hardwood inserts.

Measuring 9.12 inches long overall, the new SP101 weighs only 29.5 ounces and is perfect for self-defense in the field and at home. Chris Killoy, Ruger’s President and COO says, “The SP101 has a reputation for being a very strong and reliable revolver and combining it with the powerful .327 Federal Magnum cartridge creates a perfect ‘kit gun’ package.” Ruger’s MSRP is listed at $719, but street prices are expected to be lower.

  1. Glad Ruger brought back the SP101 in the 327 mag , putting my gun guy to ordering me one . Perfect for my wife to handle and I will enjoy this one also, probably will have to get one for myself too.

  2. If you compare the ballistics the 327 is a little bit less but more enjoyable to shoot with a lot less recoil and noise. I’m sure you will like it

  3. “Based on the .32-caliber bullet, but loaded to higher pressures, the .327 Federal Magnum performs better than the .38 Special, .357 Magnum or 9mm. ”

    Does this cartridge really perform better that .357 Magnum? I guess that begs the question, what is meant by “performs better”?

    1. More rounds on target faster and more accurately with an equal total amount of delivered energy.

      If you can put 7 of these closer to point of aim in the same time as 6 .357s, then this round is a better choice.

      Less hearing damage is nice as well.

  4. I have had a SP101 in .327 mag, with the 3 1/16th inch barrel for a few years now, a very nice shooter. I also have a S&W J frame in .327 mag, with a 2 1/8th inch barrel, which is my carry gun.

    It is easier to get .327 mag and .32 long now than it was a couple years ago. This is a fun, hard hitting round, and the gun is versatile enough to shoot .327 Mag, .32 H&R Mag, .32 long and short.

  5. I have a 2in. Taurus .327 and I’m sure I’ll have this new one in 4in. The .327 is a great round plus you can shoot all the .32’s also.

  6. Got the earlier SP-101 in .327 and love it. Accurate and powerful. It likes the Gold Dot ammo in either 100 or 115 grain

  7. I love mine so much I went out and got single seven in 327 fed mag. Being an early proponent of this round I can tell it was killed by lack of ammo and brass not anything to do woth the round itself. This has since been corrected.

  8. I like Rugers and my first handgun was a stainless Security Six in .357Magnum. I understand the philosophy behind the .327 for more capacity and power. Might be worth checking out.

  9. You got me. Never quickly read a computer screen with eyes old enough to collect Social Security without wearing your glasses.

    My SP101, in a more prosaic .357/.38 caliber, has served me well. Its comforting presence has more than once allowed me to smile when I would otherwise have been sweating.

    1. “Originally introduced in 2007 and later discontinued, Ruger is pleased to announce the return of the SP101 revolver *chambered in .327 Federal Magnum*…” I think he was referring to the SP101 in .327FM in 2007, not the SP101 overall.
