I bought a SD9VE last year and notice every time I shot arround 50-100 rounds I end up with a painful trigger finger, almost feels like bruising on the very bottom of my trigger finger.
To also put this in perspective I am 6'6 and have large hands.

I never have this issue with my 1911's or my P08, I am wondering if this issue is specific to the SD9, all polymers or a combination of large hands and polymers.

I have shot a couple rounds though a glock and never experienced this but that could have been due to the low round count.
