Well, the Pachmayr speed-loaders arrived yesterday. The good news? Amazon had them to my doorstep in about 36 hours.
Now for the rest of the story. They present as a well-made, sturdy tool with smooth and easy detent stops. They work very much like the HKS loaders, with a more stalwart "star wheel" that pivots to retain/release cartridges. In fact, it is so stalwart that IT DOES NOT ALLOW MY CARRY LOADS TO BE SNAPPED INTO OR RELEASED FROM THE LOADERS except with forceful twisting. THAT WILL NOT DO--AT ALL. In fairness, this is only one make of OEM carry ammo (Rem 125 JHP +P), and I will mess around with other brass makes today to see if those work better--but for now these are a NO-GO for carry usage. HKS loaders and Speed Strips are known and proven items. Summed up--the jury is still out.
