The HKS 57M M Series Metal Speedloader is built for shooters who need to reload a S&W Model 57 or 58 revolver fast—whether you're running drills at the range, competing, or in the field. This speedloader holds all six rounds for .41 Rem Mag and uses a simple twist-release mechanism to drop cartridges directly into the cylinder. Unlike fumbling with individual rounds, a speedloader keeps your reloads smooth and your hands on the gun.
What sets the HKS apart is its hybrid construction: the body is lightweight polymer for reduced weight and ease of handling, but the cartridge-holding points are strong metal that grips each round securely until you're ready to load. That matters—you need reliable retention during movement, in a pouch, or under stress. The knurled aluminum knob gives you a positive grip even when your hands are wet or gloved, and it's substantial enough to locate by feel alone in a rapid-reload situation.
HKS speedloaders are manufactured in the USA, and this one carries the no-nonsense design that's made them standard-issue for revolver shooters for decades. Whether you're a .41 Rem Mag enthusiast running a classic magnum or working with a modern Ruger revolver in the same caliber, the 57M delivers the same function: get your rounds in the gun without looking down at your hands.

Frequently Asked Questions
Will this speedloader work with my Ruger revolver in .41 Rem Mag?
Yes—the HKS 57M is designed to fit S&W Models 57 and 58 and compatible Ruger revolvers chambered in .41 Rem Mag. If you're unsure about your specific model, confirm your revolver's make and model before ordering.
How many rounds does it hold?
The 57M holds six rounds, matching the standard cylinder capacity of the S&W 57, S&W 58, and most .41 Rem Mag Ruger revolvers.
What's the difference between this speedloader and just loading rounds by hand?
A speedloader lets you drop all six rounds into the cylinder at once with a simple twist, then remove the loader. It's faster than seating each round individually, keeps your focus on the gun during reloads, and is especially useful during training, competition, or any scenario where reload speed matters. The secure metal points also keep rounds from falling out while it's in your gear.
Is this speedloader durable enough for regular use?
The HKS 57M combines a lightweight polymer body with strong metal cartridge points, designed for reliability through repeated use. It's made in the USA and built to HKS's proven standard—the brand has been the go-to for speedloaders among revolver shooters for decades.
