Welcome to the forum and congrats on a great weapons choice. The SD40VE was my first pistol and continues to serve the role of my nightstand home defense gun. When I got it, I got caught up in the "make it better" hype and made a few changes to the gun. Notably, I did the Galloway Spring kit because I thought I needed to reduce the trigger pull. It did, but in hindsight, I kinda wish I'd left it factory and just learned proper trigger control with the heavier trigger. I think that, in the long run, that would have made me a better shooter with a wider variety of weapons. I also replaced the takedown lever with a wider one and that I would still recommend. Working the stock lever is a finger buster, the replacement is easy, and it's inexpensive. If this is to be a home defense weapon, you should give thought to a rail mounted flashlight.
As to ammo, stick with name brands. In my case, my SD40VE shoots just about any name brand I give it. The only thing it didn't like was some Fiocchi JHP's I bought trying to be cheap. Never again. Multiple FTF's with that stuff. I shoot a ton of WWB for target and Remington Golden Saber JHP's for SD.
Last point. Clean it, even though it's new, lube it according to the manual, and shoot the heck it of it. It's good to start with and will only get better. Enjoy and be safe.
