The Shield's are great concealed carry guns. Excellent for that purpose. But if you are not planning on carrying it, there are better guns for other purposes.
But one thing to remember, "Cheap guns are cheap for a reason". Rarely will you encounter that "undiscovered diamond in the rough" we all hope to find at a bargain-basement price. You don't have to go super expensive, but don't go "the cheapest gun you can find" either. The SD9VE might not be that, but it's pretty close. The SD9VE is not a gun that you see often. You may hear them described as "A good gun
for the price". You might want to ponder why that is before buying one.
Many people buy Glocks. But to me, those are so boring. They are the Ford Taurus of the gun world. Yeah, they work. Yeah, they are reliable. They are ugly. Ergonomics are terrible, they feel like you're holding a brick. They're not going to razzle-dazzle anyone or turn any heads. But they do work well and are reliable. For the same money as a Glock, or probably even less, you can get a really nice gun - say, an HK VP9 or a Walther PPQ. The S&W M&P's are good guns too, but I don't put them in the same class as the HK or Walther that I mentioned.

The Shield is a GREAT first gun, IF it is for concealed carry. That doesn't sound like what you want it for, so I'd look elsewhere. You didn't say what "truck gun" means to you either. What exactly do you plan to do with it? Plink? Hunt? Self defense? Something to be left in the truck always, seldom shot or maintained?
Depending on what you want the gun for, you might find something totally different - like a used Ruger Blackhawk - to be just the ticket. Or even an S&W Victory or Ruger SR22 (if target shooting and plinking is mostly what you want it for). You should define "truck gun" to get the best recommendations.
