I do not place my "pinky" on the magazine but actually I place it under the base plate.
Much more comfortable for my large hands.
I too noticed that the magazine could be influenced by pulling on it with your little finger and I thought that it could cause feed problems.
It would be interesting to see if there are any problems with this gun after altering how it is held.
