Don, I’ve had to fix two Cobra derringers with this issue. The problem I’ve found is chambers reamed with dull reamers. This is an issue your local gunsmith can address or if they can’t, let me know and I’ll be happy to help.
But, with that being said, yes, Cobra is a low end product that I do not recommend to my customers.
Sometimes I think I’m a snob when it comes to guns but then I remember things like what you’re experiencing and I put the feeling of snobbishness away.
Thank you for not being snarky. I posted this article to inform others who may not be aware of my lack of quality experience with Cobra. Never would I assume to be a SME on gunsmithing. Not even close. I have tried to smooth out and reshape the extractor using a Tipton vise and a Dremel tool. If this does not work I would be happy to ask you for your address to send the weapon to you to repair. Of course I would expect to pay you for your time and for shipping.
