From what I've heard, the frame issues were with the early 1st generation models.  Before you transfer the gun to your name, make sure you eyeball it for any obvious problems or cosmetic defects.  Once you transfer it, it's no longer a new gun, it's used. You might even want to cycle a snap cap thru it if they'll let you. Also, check to make sure all the mags are there, and the key as well.
Take it home, field strip it, and give it a good cleaning. Then you should be good to go!
