I very recently did a trigger job on a Ruger 1911 for a friend, and can attest to them being tight. This same gun just 3 days later was fired with an accidental double charge. Blew the base out of the round, set off the next two rounds in the magazine, split the grips, blew the magazine out to the gun, ejected either a slug from the burst rounds or a case that hit the shooter in the right cheek just below the eye. The shooter is fine, has a small piece of material in his cheek which was removed yesterday. Unbelievably, the Ruger 1911 "seems" perfectly fine. No swelling, no cracks, the barrel and slide are as smooth and free as prior to the incident. I would almost bet you could load it up and it would function fine. The shooter did contact Ruger and they advised him (wisely) to not shoot the gun and send it in to them for inspection.They did send him a prepaid mailing label. I will be very curious what they find and if he gets that gun back or a different one. I have reservations that the warranty would cover any damage as it was a hand load, but we will see.
I am very impressed with the sturdiness of the Ruger 1911, handling a double charged load with no outward evidence of any damage.
