Maybe old news to some but I saw this on the 10-8 website today:
https://www.10-8performance.com/blac...s-qls-adapter/
This should not only allow the Blackhawk to work with the QLS systyem but also with the Safariland UBL mounts. Not that that, in and of itself, is probably a big deal but the various lengths of Safariland belt loops might give some customization over ride height. It should also allow the Blackhawk to be mounted to the True North MHA.
*note that True North has an Ominvore MHA adapter plate but he says his plate may not work with all versions of the T-Series. Also, Blackhawk is showing a new QD adapter for the T-Series on the website. It looks like it might be a little slimmer and trimmer than the QLS.
