About This Firearm

Fifteen rounds of .380 Auto in a compact frame. The Ruger Security-380 is the highest-capacity .380 on the market, matching what most 9mm compacts carry. At 19.7 oz and 6.52" overall, it is built around a hammer-fired Secure Action trigger with a 4.5 lb pull, the lightest in the .380 compact class. The internal hammer design gives it a consistent pull every time, and Ruger added both an integrated trigger safety and an external manual safety for people who want a second layer.

The extra weight compared to pocket .380s like the Sig P365-380 (15.7 oz) and the S&W Bodyguard 2.0 (9.8 oz) is the trade you make for 15 rounds and manageable recoil. Owners report the Security-380 shoots flat for a .380, which makes sense given the mass. The fiber optic front sight is a genuine upgrade over the basic white dots most .380s ship with, and the accessory rail accepts lights if this pulls nightstand duty. The 3.42" barrel is shorter than the Beretta 80X Cheetah's 3.9" barrel, but you get nearly the same overall length (6.52" vs 6.8") in a gun that weighs 5.3 oz less.

Ruger originally built the Security line in 9mm, and the Security-380 borrows that platform's ergonomics and sight setup while chambering a softer-recoiling cartridge. This made it an immediate hit with shooters who wanted full-size capacity and handling in a lighter-recoiling package. For anyone who has struggled with 9mm snap in a compact gun, the Security-380 delivers familiar magazine capacity with noticeably less wrist fatigue.

Best For

GOOD
Concealed Carry
At 1.02" wide and 19.7 oz, it conceals under an untucked shirt with a proper IWB holster. The 15-round capacity means fewer reloads in training and more rounds available in a defensive situation than any other .380 on the market.
GOOD
Recoil-Sensitive Shooters
The 19.7 oz weight absorbs .380 recoil well, and the 4.5 lb Secure Action trigger is light enough for shooters with reduced hand strength. Reviewers consistently note this is one of the softest-shooting .380s available.
FAIR
Home Defense
The accessory rail takes a weapon light, and 15 rounds is serious capacity. But .380 Auto is a marginal home defense caliber compared to 9mm. If this is the cartridge you shoot well, it works. If you can handle 9mm, a Ruger Security-9 gives you more terminal performance.

Strengths & Limitations

Strengths
  • 15-round capacity is unmatched in .380 Auto and ties most compact 9mms. The Sig P365-380 carries 10, and the Beretta 80X Cheetah carries 13.
  • The 4.5 lb Secure Action trigger is the lightest factory trigger in the .380 compact class. Owners report a smooth pull with a defined wall.
Limitations
  • No optic cut. If you want a red dot on a .380, the Sig P365-380 and Walther CCP M2 both ship ready.
  • Ships with only 1 magazine despite the competition (Sig P365-380, Walther CCP M2) including 2. Ruger's 15-round magazines are not always easy to find in stock.

Frequently Asked Questions

What is the difference between the Ruger Security-380 and the Ruger Security-9?

Same frame size and ergonomics, different chambering. The Security-9 fires 9mm Luger with 15-round magazines, while the Security-380 fires .380 Auto with 15-round magazines. The Security-380 has noticeably less recoil, a lighter 4.5 lb trigger (vs about 6 lbs on the Security-9), and is designed for shooters who find 9mm uncomfortable or difficult to control.

Does the Ruger Security-380 have a Lite Rack slide?

Yes. Ruger designed the Security-380 with a Lite Rack system that reduces the force needed to rack the slide. Combined with cocking serrations front and rear, it is one of the easiest .380 slides to manipulate. This is a real selling point for anyone with arthritis or limited grip strength.

Can I carry the Ruger Security-380 with the manual safety off?

Yes. The external manual safety is optional to use. The integrated trigger safety prevents the gun from firing unless the trigger is fully depressed, so carrying with the manual safety disengaged is a supported configuration. Many owners treat it as a decocker-style carry gun with the safety off.
