As with all EXTRACTOR double purchases, when your about to lay your money down, even on a Smith...after removing the barrels, using your thumb, press a penny against the standing breech, over the firing pin hole and let 'er rip....try to press Lincoln's face right over firing pin hole so that you can read the dent afterwards...hammer or hammerless, this system works well...do not use this system on ejector guns, and do not do this until your just about to lay down your money
If you begin this test with the safety on, you can test the safety, the strength of the mainspring, and the firing pin all at the same time.
