Before I ask this question I want to say that I did a brief search and did not find my answer.

Why did the cocking piece on the No4 not have a shoulder or rim on it for better grip? To me it seems like a de-evolution in progress over the older rifles. Even with the grooves on the piece, there does not seem to be the control. I do know of some people who have allowed the piece to slip while releasing the mechanism.

I should qualify that my mindset is one more of recreation than military so I could be missing something there. I should also plead ignorance when it comes to knowing if certain factories did this while others did not in the same period. I am merely making an assumption that No1 and 4 were different.
