Hello, and welcome to the S&W forum. There's a lot of choices out there. These two are probably the most commonly used for quicker J-frame reloads. Either way, good luck -Rob
Safariland COMP-1 Speedloaders are a little more user friendly:
Safariland COMP-1 Revolver Speedloader Charter Arms, S&W 5-Shot 38 Special Polymer Black - MidwayUSA
I prefer Bianchi Speed Strips (for pocket carry) though:
