I'll stay with my statement that both brands have terrible triggers, and elaborate on it a bit to say that it pains me to admit that generally I can manage the stock Glock trigger much better than the stock M&P trigger.

The actual shape of the S&W trigger "feels" better to me, and I have never been pinched by an M&P trigger like I get by Glocks, but the action of the trigger is very tough to manage. I find the Glocks a bit easier. I find the "trigger dingus" of the Glock to be "despicable."

If you started with the NY trigger, I can well understand that anything seems like a huge improvement.
