In recent years, I have found that nothing is called true breakthrough. Even the basic issues such as dual load protection, faster bullet up mechanism ... many manufacturers still can't do it. Actually, about 5 years ago, there was a product that did it, but then it had to stop producing because of silly errors. But I know that, even though it is faulty, you still love it and own it. In the 2019 iwa, I hope there will be breakthrough products that make a difference.
