Clean, lube, do some dry firing, and shoot a few hundred rounds. Presuming the gun is reliable and shoots fairly well, you'll be in a better position to judge whether or not any gunsmith enhancing is necessary.
While it can certainly be fun to customize guns just because you can, you'd probably be better off establishing a baseline of performance with the stock gun before having any work done, and any work done should address specific issues.
Just my opinion.
