The OP, in post 5:
I really like the beaver tail because to me it feels to minimize that Glock hump/grip angle a bit.
I don't doubt you had the slide bite issue, I have just never heard of it with a Glock before.
My main problem with Glocks has been the trigger guard shape. Bruises my middle finger's knuckle.
Onlu other gun that has done that to me was a Ruger SBH with the squared back of the guard.
