Feels like I just bought my g19 gen 4. Haven't shot it yet. Are they quickening the introduction of new versions? And as for the S&W Shield. The best tiny pistol I've ever owned. Bought it used from a member here. I like it enough that I'm on the look out for a M&P 2.0. I haven'y even considered an S&W semi auto since the 3rd gens. But they have really made a great product at a bargain price. Not to mention the made in USA part of the equation.
