Are you not shooting with both eyes open? No, I tried and found it difficult, could not get a good site picture.
Are you not shooting Modern Iso? Yes
Are you sure you know which is your dominant eye? Yes
First question is why don't you like plugs? Everyone I've met that hates plugs doesn't know how to insert them, once they figure that out, they never switch back. My wife and kids all now use plugs at the range and love 'em.
Second, try both eyes open again. It's not going to work instantly, it will take a few hours to get used to - then you'll love it.
