This set helps you properly tune the extractor on your favorite semi-auto and eliminate extractor and feeding problems before they start. Simply insert the machined brass gage between the extractor and the breech face and measure the resistance required to pull the gage free of the breech face with a trigger pull scale (sold separately). The trigger pull scale shows the exact amount of rim tension and clearly shows when your extractor needs adjustment for the proper amount of tension. Double ended gages work for 9mm/38 Super and 40 Caliber/45 ACP. This set works for most semi-auto handguns with exposed extractors and open breech faces.
