Yep, I've tried different configurations, some with extended beaver tail grip safeties, some with the overcurve frame additions and such. Some feel better than others, but the problem does persist, albeit less noticably so than in the typical stock or combat configuration.
I used to be nuts on with my buddy's officer's model. One time we were shooting at plastic jugs, he with his Victory knock-off Thompson and me with the officer's model. He emptied half a stick of ammo without hitting a particular jug, as I was reloading a mag for the pistol and stuffing it in the grip and cycling a round. I pull up on the jug, punch a hole through near center, and move to the next target. I thought for a moment he might wrap that barrel around a rock after that one. Had I chuckled or said something smart about the relative marksmanship, I am sure it would've been my head he'd have contemplated instead of a rock.
Funny thing about my Springield, it always preferred ball ammo, whereas the Glock really likes JHP, especially the Hydra-shock kind.
