HKS MK3-A Speed Loader 6rd .38/.357 Mag Ruger Security-Six Colt

The HKS MK3-A speed loader delivers rapid cylinder reloads for .38 Special and .357 Magnum revolvers in high-pressure situations. This precision-engineered loading device cuts reload times from 30+ seconds to under 5 seconds, providing tactical advantages for law enforcement, competitive shooters, and armed citizens who depend on wheelgun reliability.

What Makes This Different

Unlike basic speed strips or loose cartridge carriers, the MK3-A features HKS's patented twist-release mechanism that drops all six rounds simultaneously with a simple knob turn. The machined aluminum construction withstands repeated use without the cracking or warping common in polymer alternatives. Spring-loaded cartridge retention ensures rounds stay secure during movement while releasing cleanly when needed.

Key Features

• Holds 6 rounds of .38 Special or .357 Magnum ammunition
• Machined aluminum body with black anodized finish resists corrosion
• Compatible with Ruger Security-Six, Colt King Cobra, and Colt Peacekeeper revolvers
• Twist-release knob mechanism drops all cartridges simultaneously
• Spring-loaded cartridge retention prevents accidental spillage
• Compact 3.2-inch length fits most duty belt pouches
• Weighs 2.1 ounces loaded, 1.3 ounces empty

Practical testing shows the MK3-A reduces cylinder reload times to 4-6 seconds compared to 25-35 seconds for individual cartridge loading. Competition shooters report consistent sub-5-second reloads after minimal practice. The aluminum construction survives thousands of loading cycles without mechanical failure, while the anodized finish resists wear from repeated holster contact and environmental exposure.
