Seized-up S/42

[mloula]

Everyone, Thank you for the prompt replies and the welcome! I do in fact know how to disassemble a Luger, my problem is more that I am unable to due to it being seized up. There is some pitting on the gun, and after taking the grips off, I can see some surface rust on the inside as well. The mainspring is in good shape, as well as the safety mechanism and everything else that I can see. I am 100 percent positive that this is a rust issue. I have tried many times to get this disassembled, but I have had no success yet. This is not at all a museum-quality gun, just something I would like to get to shooter-status; however, I am not dead-set on making this a shooter. If it turns out to be too dangerous or altering the weapon too much from its original state, It will look good next to my 1911 as nothing more than a antique mantelpiece. My real question, as stated in my original post, was whether or not there is some type of solvent/oil out there that is safe for antique firearms like this. Like I said though, I won't take any unnecessary risks if it just can't happen. I have owned many firearms, and have always practiced safe shooting. I have just never had an experience like this before, so I decided to consult the luger authorities. Thanks again for your help guys!
