If I may add to Ron Woods excellent advice, anyone wishing to take their vintage Luger or any collectible firearm to the range please first take it to a competent Gunsmith that has experience in that particular line of firearms, especially Luger's. There are several very competent and knowledgeable people on this forum that for a relatively small fee will go over your Luger for you and determine weather or not it is safe to shoot. I say this after shooting my 1917 all matching Artillery and causing irreparable damage to the barrel extension. I highly recommend Tom Heller AKA Luger Doc at
hellerarms@webtv.net to do the inspection for you, he does excellent work and is a highly respected member of this forum.
