I am new to this forum and have a question about extractor for a model 910. I inherited a model 910 (as a box of parts). As for as i can determine, the only part missing is the extractor. I have tried to find this at Numrich, Midway, and Brownells. No one seems to have a listing for that part. Was just wondering if this is a part shared by other models or is it specific to the 910? Is there anyone that may be able to help me find this extractor? Thank you in advance for any help.
