I don't see any particular advantage over the HKS
style of speedloader, and I see one disadvantage: added "volume" because of the hand-grenade type of release.
He even had difficulty aligning the cartridges in one instance, just like in the HKS
style of speedloader:
It also looks like because of the complexity, they'd be pretty expensive, but when you're talking safety devices, hang the expense.
I've tried various speedloaders including the Bianchi straight-strip type, and given the various +es and -es, the only real complaint I have for the HKS ones is that the release is counter-intuitive in that you turn the knob
clockwise to release the bangy bits. That somehow, for me, violates the lefty-loosey-righty-tighty rule. I understand that another maker of the HKS-style reverses that, so a counter-clockwise rotation releases the cartridges.
I was tempted to take my HKS loaders apart and relocate that little pin so they'd release with a CCW rotation, but I got so well-trained in the CW rotation that I decided not to change things. I have HKS loaders for every revolver I own.
However, truly it has been said that the fastest reload is to have another loaded gun ready-to-hand.
