I'm just finding out about this and I'm having a hard time believing it.
One of my local clubs (I'm a member at almost all of them) asked the uspsa match director for a list of everyone that has been DQed from every match. He asked them what they wanted that for because he would have had to figure it all out. They replied that they would give the list to the state police so if anyone ever had to use a firearm for non sporting reasons they would be labeled unsafe to use/own firearms.
When I first hard of this I didn't believe it but was told that another club in PA was doing the same thing. Then proceeds to tell me of a story of a guy that got into a lot of legal trouble because of it. I don't think I should post those details here.
Where did you buy them from? I just Googled it and a place called dot 40. Net popped up? Ever heard of them? Here's the link https://www.dot40.net/product/competition-extractor-for-1911-2011/ theres no street address on the website
