The HKS Model 586-A Speedloader is a mechanical loading accessory engineered to charge six-shot medium-frame revolver cylinders simultaneously. Constructed with a durable black polymer body, internal metal retention pins, and an aluminium knurled twist knob, the loader holds cartridges securely in place during transport. Once aligned with the cylinder, a slight turn of the knurled knob releases all six rounds instantly, significantly reducing reload times during range sessions and practical shooting disciplines.

Key Features

• Twist-Knob Release: Utilises HKS's mechanical twist-action release to drop all 6 rounds into the cylinder instantly upon rotation.
• Positive Cartridge Retention: Internal metal locking pins secure cartridges firmly inside the body to prevent loose movement and accidental discharge from the loader.
• Durable Construction: Combines an impact-resistant polymer housing with an aluminium knurled knob for reliable mechanical operation without electrical components.
• Pouch Compatibility: Formed to standard medium-frame dimensions to fit common medium-sized speedloader belt pouches and cases.

Who is the HKS Model 586-A Speedloader for?

• Practical revolver shooting competitors — who need to load a full capacity of 6 rounds of .38 Special or .357 Magnum ammunition in a single action to minimise stage times during IPSC, ICORE, or club matches using this revolver speedloader.
• Revolver target shooters — who require rapid, consistent bench reloading of 6 rounds of .38 Special or .357 Magnum cartridges directly into compatible medium-frame cylinders.
• Duty and security personnel carrying revolvers — who rely on this speedloader to carry a secure 6-round reserve of .357 Magnum or .38 Special ammunition held firmly by internal metal retention pins until mechanically released.

Less suitable for: Revolver configurations outside standard 6-shot medium frames, such as 7-shot L-frame variants, S&W K-frames, and S&W N-frames, which require frame-specific 7-shot or larger/smaller frame-dedicated speedloaders, as well as revolvers fitted with thick target or oversized grips lacking adequate relief cuts for straight cylinder insertion.
