I recently picked up this older Model 36 with factory banana grips; I was surprised as to how good they feel and how well the revolver points with them. Probably not the best if you are trying to conceal it though.
I have an M&P Pro 9 and an M&P 40 and in my opinion the trigger on the Pro 9 is so much better than the standard M&P 40, so good that I don't even want to do anything to the Pro, the M&P 40 will get Apex trigger parts in it some day.
