I have posted these pictures in the past and decided it's been a while and there are probably some that have never seen them.

Pictured below is the the Hamilton Zip Set speedloaders for the K22 revolver.

These were manufactured in the 50's and were used at the ranges for competition shooting. They work rather well even though the technology is rather antiquated.

The series of pictures should give you a visual on how they function.

Enjoy,
