Luger not shot in 25 years...is it safe?

[DavidJayUden]

F:
Snug up the grip screws, lube the toggle assembly and the tracks that it slides in, lightly clean but do not oil the barrel. Give it a good visual inspection. If the magazine has a wooden bottom, pick up an aftermarket such as a Mec-Gar.
Use a pistol rug case and leave old leather holsters at home.
Use great care and patience when removing the left grip panel so you don't chip off the upper rear corner.
Use the ammo. already recommended.
Dry fire it a couple of times to be sure it clicks as it should. Lightly clean the insides of the side-plate, trigger/firing striker/etc. if it feels or sounds gummy.
Load and fire just one shot at a time for a few rounds. Inspect the gun after each shot, examining the brass for bulging or signs of pressure, and check the holes for signs of keyholing.
Just use good common sense and let us know how it goes. Unless it breaks, then I'd not mention that...
