I posted this else where as well, but wanted to try here also. Guys I talked with an after market barrel co concerning putting a 'conversion' 10mm barrel in a G30. They said the extractor will have to be filed down in a certain place for 100% function (extracting empty brass). Problem is he did not know where to file the extrator ! Any one give me a graphic on this ? Like take a pic of the extractor out of the gun, point to the place with a pencil et. Give me some specific details please. Greatly appreciated.
