Die hard Glockist here. Love the reliability but not in live with the 2x4 feel. Gen. 4's are better I admit. In spite the the TX DPS horror story I purchased an M and P Nine last week. I wanted a Nine Milli with coventional rifling versus the polygonal rifling on a Glock so I could run lead, non-jacketed billets if need be.
I post back with impressions and performance once I take delivery and shoot it a while. They feel good in the hand but I am addicted to that Gloxk trigger reset.
