Big sigh...
So.
1st thing. If I hold it in place,and pull the trigger l. it feeds better than I expected and I'm actually impressed.
2nd thing.
So using a soldering iron I deepened the well. It almost works...
Then I wrapped duct tape around the top of the mag.
Now it kinda works... Basically it's jammed in and takes a good tug to come back out....
So. Some level of success.
Thanks all.
