Locally, I see used M&P's going for under $400. I paid $350 for a FS Gen 1 9mm with thumb safety. It had the old 1/16 sear spring housing which I replaced. The part cost $50 and was out of stock at all the usual places. I found the correct part on EBay. Now I can install an Apex trigger kit. I have only test fired it and found the trigger to be pretty heavy. I will eventually test for accuracy and if poor, I will invest in a barrel. The sights are the original Novak's with dim tritium and may need replacing too. So my bargain may be expensive in the long run. I knew this going in after reading all the threads here. I am starting to think of the M&P as the 1911 of striker fired pistols.
