The 15T is a very good choice. I bought S&W because of a brand loyalty developed over many years. Now that S&W is actually doing most of the fabrication in house, I think it has become even more attractive a choice.
My high end choice would be LMT but you get (IMHO) at least 95% for half the price. I think the sport is agood buy too but not the mid price point you want. I am pretty much in tune with that outlook too.
