The revolver's honest weakness is the reload, and the speedloader is a hundred years of refinement aimed straight at it: all your chambers charged in one motion instead of six. But walk up to a speedloader display cold and you meet the catch immediately — a wall of near-identical discs with cryptic model codes, each fitting some revolvers and not others. Here's how the fit system works, which loader goes with what, and the practice that turns the gadget into an actual skill.
Why there's no universal speedloader
A speedloader must align a circle of cartridges with your cylinder's exact chamber spacing, clear the grip and frame during insertion, and release cleanly — and every one of those dimensions varies by revolver frame, capacity, and caliber. A five-shot compact and a seven-shot service gun are simply different geometry problems. So the industry runs on fitment codes: each loader model is built for a specific list of revolvers, and the entire buying task is matching your gun to the right code. Get that right and everything downstream is technique; get it wrong and you own a paperweight.
The HKS system, decoded
HKS is the century-old standard of the twist-release school: cartridges hang in the loader, you seat them into the chambers, twist the knob, and gravity does the rest. Their catalog looks intimidating and is actually simple — each model number is a fitment answer. The HKS 36-A covers the enormous five-shot .38/.357 compact class: Taurus 605s and 856-pattern guns, Ruger's small frames, Charter Arms, Rossi, and the classic S&W J-frames — if you own a common carry snub, this is very likely your loader. The HKS 587-A handles the seven-shot .357 L-frame class typified by the S&W 686 Plus and compatible Taurus models. Colt's classic D-frames and Pythons have their own dedicated fits in the line. The buying procedure is always the same: confirm your exact model appears on the loader's fitment list — not "looks about right," appears on the list — and when in doubt, browse the full HKS collection by your gun rather than by loader model.
Technique: the part the gadget can't do
A speedloader reload is a sequence, and speed comes from sequence discipline, not hand speed:
- Empty decisively. Cylinder open, muzzle up, one firm palm stroke on the ejector rod. Half-hearted ejection that leaves a case under the star is the number-one reload failure, and it happens at the step everyone rushes.
- Muzzle down, loader in. Gravity now works for the cartridges. Guide the loader by touch — bullet noses find chambers better when your eyes stay up and your grip on the loader stays relaxed.
- Release and let go. Twist (or press, on push-style loaders) and drop the loader. The spent loader is trash until the string is over; hanging onto it is the second most common time-leak.
- Close, don't flick. Swing the cylinder shut with the support hand. The movie flick is theater that your crane will eventually bill you for.
Practice the cycle dry with dummy rounds until it's boring, then add pressure gradually. Wadcutter shooters, budget an extra beat — the flush profile our wadcutter guide covers doesn't self-funnel like round-nose ammo.
Carrying the reload
A speedloader loose in a pocket collects lint, rotates constantly, and presents backwards at the worst moment. A proper carrier fixes orientation and access — the HKS double loader pouch holds two charged loaders indexed and protected, which for range and field use is the difference between owning speedloaders and actually having them. And buy loaders in multiples: one on the belt, one in the range bag, one living charged with practice ammo for dry work. They're cheap insurance against ever practicing the skill less because the gear wandered off — the full speedloader board makes stocking up painless.
Bottom line
Match the code to your exact revolver, learn the four-step cycle until it runs without thought, and carry the loader in something built for it. The revolver's reload never becomes a magazine swap — but a practiced hand with a fitted speedloader closes the gap far more than the round-count crowd wants to believe.
Frequently asked questions
How do I know which speedloader fits my revolver?
Speedloaders are built to exact fitment lists — match your revolver's exact make and model against the loader's stated compatibility, not its general size. HKS model codes each cover a specific set of guns; the 36-A, for example, fits most common five-shot .38/.357 compacts.
Are speedloaders worth it compared to speed strips?
They solve different problems. Speedloaders charge every chamber in one motion and are the fastest full reload; speed strips are flatter and more concealable but load two rounds at a time. Many revolver carriers run a speedloader where it can be carried properly and strips where flatness rules.
Why does my speedloader release before the rounds are in the chambers?
Usually grip pressure — squeezing the loader body or bumping the release knob during insertion. Hold the loader lightly by its body, seat the bullet noses into the chambers first, and only then actuate the release.
