"This Gun"
Shitty gun is shitty. I would put it in as a down payment for a better gun. Such a Glock 18. I would then buy quite a few boxes of ammo for my Glock. After that I would proceed to take the Glock apart to clean it, and remove the spring. Removing the spring would make the gun fully automatic instead of semi automatic. It would be easy to hide as well due to it's small size.
I would then go and rob every anime store in the area for anime, manga, doujins, and collectibles.
