I'm sorry...I'm not following you. I dont see where you're coming from. my mag button and my pinkie are not anywhere near each other.
I am right handed. I have a pro pt140. my mag button is on the left side of the grip, much closer to my thumb than my pinkie, and my pinkie on my shooting hand (right) already puts rear pressure on the mag. not even close to putting down pressure on it.
Honestly, with my 3rd Gen mill pro 140, I don't see this happening. Am I just that new, or do others concour?
I have shot my friends 140 1st gen, where my pinkie did not come in contact with the mag in a comfortable place, therefore it sat on the bottom of the mag creating more of an up pressure, where I could possibly see what you are saying. But then again, my thumb never came close to the mag release.
but on my 3rd gen, the grip and mag are long enough so that my entire hand fits the grip and the mag. Nothing "hanging" below the mag and no fingers close to the mag release.
and I have big hands. I'm sorry, I'm just having a hard time with "allowing my pinkie to put rearward pressure on the mag instead of downward." It should always be rearward. Sorry, I think I might be lost....
