I think the AP bands conversion adaptors fit more straps. I have an oracle strap with conversion kit and I suspect it doesn't work with all straps. I took out the oracle adaptors and tried to fit it onto an MBW rubber strap with deployant and it won't fit. The end of the adaptor that's supposed to connect to the strap isn't flush like the AP bands conversion kit. Could it just be me?
None the less, Oracle straps are great!
