I purchased a SD9VE recently and I believe it is the best bang for the buck semi auto extant. The only thing I couldn't live with on my pistol was the rotten trigger. Like many on the forum I polished the feed ramp and went with the apex spring kit. Also polished a couple surfaces per the instructions in the apex video. Made a world of difference. If you have small hands the factory grip is near perfect although folks with larger mitts seem to like the ergos as well. With my pistol at least I have found the elevation POI to be very close at 50 feet with various types of ammo. A real plus when dealing with windage only adjustable sights. My 9mm feeds anything I have tried flawlessly including cast bullet loads. I'm sure you will be pleased with the 40 S&W version....
