I'm not a Glock Fanboy by any means but I have got to get me one of those 199MMs!
I want you to choose the gun I own and validate my own choice so I feel better.
Seriously, both are great guns and pretty equal in call categories. Which one feels best in your hands?
It really is comparing apples to artichokes. If possible, buy both, then decide. If not buy one see if you like it.
