I goofed trying to add a smiley so I will continue.
The HKS 587A is the only speedloader I have found
for the 686P - the length of the .357 Mag. - one round
hangs up on extraction on the upper LH side of the grip.
I kept the rubber stock grip unaltered but the Guy Hogue
grip in Coco Bolo wood I'm waiting on will be modified for
no clrearance problems.
Another thing about the HKS 587A Speedloader finding
a speedloader belt holder in leather is a bit of a pain
because HKS only comes in black, De Santis makes a tan or
black but it is designed to put 3 cartridges on each
side of the belt, so, I don't think it would work with the 587A
I'm searching for something in Cordovan to match the belt and
holster. I'll post it when I find it.
FWIW - I also have a 625 5 inch .45 ACP / AR and the
shorter rounds have no clearance problems with the grip.
with the HKS 25M for Auto RIm or Full Moon clips for ACP.
