I think the excess lateral room in the mag well may be allowing the hold-open to slip off and past the button.

More likely a weak mag spring, or a hold open that is a little tight in its cut out.

Wolf has new mag springs; the hold open may just need a little
work with some fine paper.

The hold open must move very freely in its cut out.
