NEeD HELP...

My luger from Aimco is a great gun, accurate, well finished, and a joy to shoot. I noticed some stress marks along the ejector(along the right side). Well the company is very hard to contact by phone or fax and in addition they wont have any more ejectors for 2 months. Is it possible to have my gunsmith (who machines replacement parts) make a replacement? If so what would be the best material to use. The hassle just isn't worth it--Ill just have him make replacement parts and i figure Ill have him make it before the original breaks. Any suggestions?
