I use a very good 6 inch magnafier with a 75 Watt bulb in it. carefully check the receiver and toggle assy for cracks before firing. TH I would look at every part. Inspect the gun after each shot, examining the brass for bulging or signs of pressure, and check the holes for signs of keyholing. as David says. You could easily break a numbered part, even with the proper low velocity 9mm ammunition (mentioned above) Eric..Yup! That has been the fate of many an all matching Luger.
