Taurus 738 TCPs are popular so if you don't like it you'll be able to sell it. I have not owned the 738 TCP but I have owned other Taurus guns and overall didn't have any more trouble than with any of the others I own. Good luck.
I have a newer C model myself and have no problems with it. I helped to break it in by racking the slide several hundred times. Mine will feed all types of ammo with no problems. In case you are interested in an awesome CC holster check out this style. I forget it is my pocket. Made in USA. Link Removed
Just be sure to shoot it and make sure it works correctly before depending on it for your protection. You should do this with any gun you plan on carrying.
