Smith &Wesson 586, 686, 581, 681, & Ruger GP100 type revolver speedloaders like those made by HKS and 5 Star.
Why buy a heavy, shiny, imported, metal loading block?
Drop it, kick it, throw it, etc., then pick it up and use it. It's not ruined if it falls off the range table and not heavy in your bag either. Made to stand the abuse of the shooting range!
Holds 36 Rounds!
Foam padded base to help prevent slipping and skidding.
Have your rounds ready for easy speed loader reloads.
