When you take the pistol down for a good cleaning, examine closely the locking block, barrel and when assembling pay attention to the position of the recoil spring. Good luck with it and let us know how it works out!
Edit to add...I just saw "new pistol"...remember that the clock is ticking on the warranty as regards free shipping back to Miami for repair. Being new it probably goes to cleaning and assembly...unlikely parts like the spring would be worn out.
