I have had a 97dc for years, and never got it to work well. About 1 FTF in 2 magazines is about my best. I have never tried factory ammo, but run several other Rugers and Glocks successfully on my reloads. I noticed small brass filings on the extractor yesterday, and they appear to be from where the extractor touched the smallest diameter of the case. I have added tension to the extractor years ago and thought it helped. but maybe have too much?
Any way to further quantify the amount of tension on the extractor?
Thanks
Ken
