Tried a friends' BP9 CC a while ago and was pleasantly impressed with it. I can't say surprised as the thunder CC I tried was a pleasure to shoot as well. Odd some folks think the Shield has a bad trigger, as both 9mm Shields I've owned were fantastic shooters and put the other M&P triggers to shame.
If I didn't already have a Shield and PM9, I'd be very interested in picking one up.
