If you're looking for something tough but not too pretty, go with either a glock or (my preffered polymer pistol) a springfield xd9. Personally, when shooting a DA auto, i just like using guns with external hammers. in this case, the beretta 92, a ruger p-series pistol, or a cz75 would be a good choice. I have to agree with your choice of caliber for what you'll be using the gun for, 9mm is very underrated and a case of shells can be had cheap.
