Twister: I much prefer Safariland's speed loaders. No knob to turn to release the cartridges. After lining them up with the cylinder chambers, just push a little harder & they drop in. They have Comp-1, Comp-2, & Comp-3 models. The latter pushes the cartridges in under spring pressure. Ask around for someone who uses them, so you can see the difference.

Good Luck!
