What specific revolver models are compatible with the HKS Model 51J speedloader?

The HKS Model 51J is exclusively designed to fit the 6-shot Smith & Wesson Model 51 J-frame revolver chambered in .22 MRF (.22 WMR / .22 Magnum). It will not fit 8-shot J-frames, 6-shot .22 LR J-frames like the Model 34, or K-frame .22 revolvers.

How do I operate the twist-knob release mechanism in the field?

To load your S&W Model 51, insert the six .22 WMR rounds into the speedloader and align them with the cylinder chambers. A simple clockwise rotation of the textured metal twist-knob releases all six cartridges simultaneously into the cylinder.

Are speedloaders regulated under Australian firearms laws when purchasing from XHunter?

Speedloaders are un-serialized mechanical accessories and do not require permits to acquire as a controlled firearm part. However, you must legally hold a valid Category H firearms licence in your Australian state or territory to own and use handguns and their direct accessories.

Which compatible speedloader pouches do you recommend for carrying the HKS 51J in the outback?

For secure field carry while out hunting or pest controlling in the bush, this speedloader pairs exceptionally well with the Hks Model 105 S/Leather Case Bwb or the Hks 203 Double Molded Speedloader Case in plain medium, both designed to accommodate medium-sized HKS loaders.

Revolver Speedloader - HKS HKS51J

The HKS Model 51-J Revolver Speedloader is a dedicated mechanical reloading accessory engineered specifically for the Smith & Wesson Model 51 J-frame revolver. Designed to eliminate the manual, single-cartridge loading process of small rimfire ammunition, this speedloader holds a full 6-round cylinder charge of .22 MRF (.22 WMR / .22 Magnum). Using an internal metal pin retention system with an integrated twist-knob release, a simple clockwise turn drops all 6 rounds simultaneously into the cylinder chambers. The carrier is constructed with engineered cartridge play, allowing rimfire cases to self-align effortlessly with the cylinder face during operation.

Key Features

Simultaneous 6-Round Loading: Delivers instant chambering of 6 rounds of .22 WMR ammunition to streamline cylinder reloads.
Twist-Knob Release: Utilises internal metal retention pins that secure cartridges during carry and release instantly upon turning the knob clockwise.
Self-Aligning Cartridge Play: Built with intentional cartridge movement to ensure rimfire cases align cleanly with the revolver's cylinder chambers.
Mechanical Reliability: Operates entirely without batteries or electrical components for consistent field performance.
Pouch Compatibility: Sized to fit standard medium-sized speedloader pouches and cases.

Who is the HKS Model 51-J Speedloader for?

Small-Game Hunters: Delivers rapid field reloads by instantly dropping a full capacity of 6 rounds of .22 WMR ammunition into the cylinder without manually handling individual rimfire cartridges.
Pest Control Shooters: Provides efficient management of follow-up shots with a mechanical twist-knob system that chambers 6 rounds of .22 Magnum simultaneously into the S&W Model 51 platform.
Target and Range Shooters: Reduces downtime at the firing line by using pre-loaded carriers holding a 6-round capacity specifically spaced for the vintage 6-shot S&W Model 51 J-frame cylinder.

Less suitable for: Revolvers with capacities exceeding 6 rounds (such as 8-shot .22 LR or .22 WMR J-frames), 6-shot .22 LR J-frames, or larger medium-frame platforms; these configurations require dedicated 8-shot J-frame rimfire speedloaders, dedicated .22 LR J-frame loaders, or K-frame specific speedloaders.
