Back in the 90s I was at the range trying out a Starfire in .40 S&W when a young man next to me asked me to shoot his gun. It was a police trade-in service type stainless double stack S&W 9mm with the standard DA/SA trigger. He was new to centerfire handguns and was throwing the shots wild and wanted to knoiw if it was him or the gun. I fired a few shots and it grouperd fine so I suggested an experiment, with me loading his gun with single shots and having him shoot it. Classic, right? After two or three shots I gave it to him empty and sure enough the muzzle did a massive nose dive when he pulled the trigger. No reason as recoil was very moderate in the gun, he was just unfamiliar with handguns. Had him do a little dry firing while concentrating on sight picture and follow through and then had him shoot a few magazines loaded with 3 or 5 cartridges. Just a few minutes and he was shooting groups and very happy.
The S&W was a nice gun and easy to shoot well. Like TGR my hands are too small to properly reach the DA trigger on double stack guns, and unfortunately I don't care for the Glock grip[ angle or trigger, wish I did. I do fine with single stack guns with decent triggers but it means a huge number of good police trade-ins are not useful to me. Too bad.
That S&W looks to be a fine gun and a great deal if it fits you. You can't lose at that price in any case.
