Very hard to fold - Midwest Industries Side Folder Pistol Brace Compatible

Everything about this folder is great except for the unlocking of the folder mechanism. With your thumb at the end tip of the upper rail, you will have to defeat what it seems like a car suspension spring inside the adapter in order to release it. Also, the description "Solid positive lock up in both positions" is incorrect - it does not lock in the folded position, it is under a spring tension that keeps it tightly to the side.
