What are some of those major releases that never quite managed to fix all their bugs?

What popular gun gear still has problems that manufacturers haven't really addressed?

Some of the first pistol brace designs seemed like they came out too fast before they really knew the rules. The companies fixed things later without saying much but the people who bought them first were basically testing them for the company. A lot of times, big marketing pushes happen faster than the engineering is ready.
