Any pistol will cycle and shoot every load differently. That's why you have to try a box of as many brands as you can. However, I suspect 180's are just not enough to cycle the action.
Have a look at the mag lips too.
Only shot a DE once, long ago, and I still laugh about how much too big the thing was for my hand. Finger came nowhere near the trigger. Need about an inch and a half more finger. snicker.
