At the Pistol range the other day a member was doing a test on his STI 2011. He was going to drop a round in the Chamber and let the slide slam down on it. We all had a discussion on weather that was the right thing to do. I said the round on a 1911-2011 must be stripped from the Mag, and the rim runs between the extractor hook and the Breach face.To drop the slide on a chambered round will flex the extractor past its designed limits. It might be ok for a couple of times but I sure would not do it, as it will loosen extractor tension. Any thoughts on this ???
