Before I saw you'd bought the M&P (nice pistol, BTW), I was going to suggest trying the new Gen 2 Sig 229 SAS. It's a DA/SA trigger, but the new Gen 2 version swaps out the DAK trigger for the short-reset trigger, which is a terrific trigger. After the first shot it's as crisp as a good 1911. Expensive, but good. I almost bought one last weekend.
