Rob,
I take a slightly different view from my esteemed collegue Rick. Check out this discussion
http://forum.lugerforum.com/showthre...n+parts+survey as a more cautionary approach.
Shoot any truly collectible Luger if you are comfortable with the possibility of reducing its value by several hundred dollars by doing so--it can only take one shot.
Frankly there are many respectable Lugers out there which, for one reason or another, may be shot with relative impunity. If you are looking for a truly collectible gun, don't shoot it. If you are buying a Luger to shoot, don't buy--or pay the price for--one which is truly collectible.
