Thanks for those links, I've used most of these for odds and ends in the past although I haven't heard of Zelikrovitz they seem to have a decent stock of leather.
We use a bunch of different pieces of hardware, probably 100 different sku's between belt buckles, centre bar buckles, double cap rivets, burr rivets, tuck locks, segma snaps, line 24 snaps, trigger snaps, sling lever hooks, fish hooks, key rings, grommets just to name a few - all in four different finishes (brass, nickel, antique brass, black pvd).
So yeah, it's going to be a big task replace all of our hardware with new sourcing but we have to start diverting away from BG since the price jumps last year.
Appreciate the feedback!
