So far so good. I also picked up a Glock 48 around the same time. I shot them both the same day last week. As usual, I shoot Smith M&Ps better than a Glock of the same genre. I can shoot a Glock ok but it requires more effort even tho the 48 feels way better than their double stacks. The Smith just puts holes where I'm aiming with far less effort. I have 2 gen 1 shields (9mm). 1 standard and 1 PC. the PC is my 'gold standard' for single stack 9 carry...I just shoot it well. I haven't shot the PC and the 4" side by each yet but I will. The trigger on the PC is a little better but the 4" seems to stay down on the target like the PC does so it should be interesting and fun. If your in the market and like the the 3" model I don't think you'd be disappointed in the 4" version....fwiw...
