Chiappa Firearms Rhino 40Ds Chia 340.165 9Mm 4 6R Blk

The Chiappa Rhino 40Ds is a 9mm revolver built on a distinctly different platform than traditional designs. Its signature feature—a barrel positioned at the bottom of the cylinder rather than the top—shifts the bore's centerline lower, more in line with your arm and hand during firing. The result is faster target reacquisition and noticeably less muzzle flip on follow-up shots, especially valuable in defensive scenarios where speed and accuracy matter. The Rhino's flat-sided cylinder profile keeps the gun slimmer than conventional revolvers, aiding concealment without sacrificing the reliability and simplicity that make revolvers trusted by shooters who prefer mechanical dependability.

Built from lightweight alloys, the 40Ds tips the scales at just 1.87 lbs, making it manageable for extended carry or range sessions. The 4-inch barrel strikes a balance between sight radius and overall package size, and the 6-round capacity in 9mm gives you common ammunition compatibility—a practical advantage if you're already stocked with 9x19 for other firearms. The Rhino operates in both single and double action; a hammer-cocking device lets you ready a single-action trigger pull when speed is the priority, or work the longer double-action stroke for every shot if you prefer.

Whether you're building a defensive rotation, looking for a range gun with genuinely different ergonomics, or hunting for a compact revolver that handles recoil better than its peers, the Rhino's unconventional geometry deserves a serious look. It's the kind of firearm that challenges how you think about revolver shootability.

Frequently Asked Questions

Is the Chiappa Rhino 40Ds good for concealed carry or defensive use?

Yes. The flat-sided cylinder keeps the profile slimmer than traditional revolvers, and the lower bore axis reduces recoil and muzzle flip—both advantages in defensive shooting where follow-up accuracy matters. At 1.87 lbs, it's lightweight enough for belt carry without printing excessively.

What ammunition does the Rhino 40Ds shoot?

It's chambered in 9×19 (standard 9mm), so you can use common factory and handloaded 9mm ammunition.

How does the single-action function work?

The Rhino uses a hammer-cocking device that engages the internal hammer to prepare the gun for single-action fire, giving you a shorter, crisper trigger pull without exposing the hammer.

What's the barrel length and sight radius?

The 40Ds has a 4-inch barrel and an overall length of 8 inches, providing a practical sight radius for both defensive and range shooting without an oversized footprint.
