I saw on another board that a guy had an FNX and took it to the range and fired a few rounds thru it and while waiting on a friend to arrive and firing another pistol he laid it on the bench (apparently outside range) and after laying there about 10 mins. in the sun when he went to shoot it again the pistol froze with the hammer in the cocked position. It would under no circumstances fire, however after he took it inside and it cooled off it again worked perfectly. Does anyone know if FNP's are prone to this problem? If has never happened to me but, it makes me a bit wary of using mine for CC. When he called FNH they said this was a common problem.
