These reportedly aren’t as crappy as most promag stuff. No personal experience but a few folks I know run them with no complaints. The Hahn ones are the pinnacle of quality but also cost 3x as much. I have a buddy that runs a Hahn with his M16 and it’s absolutely perfect.
For glock mag host, I’ve taken a step on the oddball side and pre-ordered a recover tactical brace thingy to use with a G19 with a red dot. It’s presently inbound from Israel.
