Battery grip D-BG4 lock/unlock lever

Recently I bought a Pentax K5 II with battery grip D-BG4. One of the first thing I noticed was the flimsy design of the lever on the battery holder lock\unlock knob, both on the camera battery compartment and on the D-BG4. It is very thin and it looks as if it can snap off at any moment when applying force.

I cannot find any threads on it so, it might not be an issue, but I still would like to know if anybody has had problems with it.

You would normally turn the lever gripping it at position A but that will torque it and stress is applied to position B where it connects to the bearing and it could tear off at that position after some time. So, as a precaution I now grip it with my finger nails as low as possible, at B, to prevent this.

The strange thing is, if you look at it in detail, it seems that someone has spent quite some time designing it, but it seems too fragile.

I have an original Pentax D-BG4 and have had problems with the shutter button (repaired under warranty) but none with the battery door.

A non-issue.

I find it 100% reliable. There isn't much torque needed nor applied when locking.

Question answered.

It indeed seems that nobody has ever broken it. Searching with Bing also doesn't return results, only my own thread at PentaxForums. I'm probably too cautious.

That answers my question.
