The Hornady Lock-N-Load Powder Measure Handgun Rotor & Metering Assembly is a specialized component for reloaders working with pistol and magnum rifle cartridges where precise, smaller charge weights matter. If you're handloading 9mm, .45 ACP, .38 Special, or other rounds that call for sub-20-grain powder charges, this rotor and metering assembly swaps into your Lock-N-Load powder measure to deliver the accuracy your loads demand. Hornady built this piece around the principle that safe, repeatable ammunition starts with consistent powder measurement—no shortcuts, no approximations.
The handgun rotor features a smaller chamber than the standard rifle assembly, engineered to meter charges between 0.5 and 17 grains with better resolution and repeatability in that range. When you're loading light pistol rounds or working with dense powders, oversized metering cavities can trap air pockets or settle inconsistently; this assembly tightens that tolerance so your charge weights stay where you set them, round after round. It's the kind of detail that separates mediocre loads from ones you trust at the range or in the field.
Installation is straightforward if you already own a Lock-N-Load powder measure—this is the rotor-and-metering-assembly swap, not a standalone unit. Drop it in, dial your charge weight, and you're ready to work. Reloaders who handle a mix of rifle and pistol loads often keep both assemblies on hand so switching between light handgun charges and heavier rifle powder dumps is just a quick swap, no tools required.

Frequently Asked Questions
Will this rotor work with my Hornady Lock-N-Load powder measure?
Yes. This handgun rotor and metering assembly is designed as a direct fit for Hornady Lock-N-Load powder measure systems. If you already own the measure, you can swap this assembly in without additional modifications or tools.
What's the difference between this and the standard rifle rotor?
The handgun rotor has a smaller metering chamber optimized for lower charge weights. While the rifle rotor handles a broader range, this assembly provides better precision and consistency when metering charges between 0.5 and 17 grains—the range common to most pistol and light rifle loads.
What calibers can I load with this assembly?
This rotor is suitable for any handgun or light rifle cartridge where your powder charge falls between 0.5 and 17 grains. That covers most pistol loads (9mm, .45 ACP, .40 S&W, .38 Special, etc.) and lighter rifle loads. Always consult your reloading manual for the specific powder and charge weights for your cartridge.
Do I need the full powder measure to use this, or does it come as a complete unit?
This is a rotor and metering assembly only—it is a swap component for an existing Hornady Lock-N-Load powder measure. You will need the measure body and stand to use it.
