[John Sabato]

Hal. you can proof test your own Luger, but there is no small amount of risk involved... first you have to do some reseach and come up with a load to duplicate the pressure and shock of a couple of industry proof rounds...Once you have loaded them, make sure you mark them with indelible marker so that you don't get them mixed up with ordinary ammo and fire them in a gun not intended for them...

Then the gun has to be mounted in the equivilent of a Ransom Rest and fired safely from a remote distance... If the gun stays in one piece after firing a couple proof rounds, then it should be fine...

But since you had a licensed gunsmith replace the barrel, I hope he knows that he holds liability for the safety of his work... If he replaced this barrel so that you could shoot this Luger... then you should be fine... If the barrel replacement was only to restore its original look... then I would beware... The gunsmith who took on the job of replacing this barrel should be able to tell you if it is safe to shoot...
