I am bummed! I really wanted these and after dremelling out the latch point for the 3+ only to have them not run! Thankfully I had a couple factory mags and p-mags so the day wasn’t a waste! patreon.com/MyTriggerTalk
It will work in the previous Scorpion models but doesn’t have the notch for the 3+. I made a jig to dremel out the notches for mine. Still never ran right.
