What model do you have? I wonder if the Tisas 45s are inherently better because all they had to do is an exact copy of existing designs. I think when they tried getting their 10 mm going they didn't really hit the target so to speak. I've seen a lot of people have issues with their Tisas 10 mills. And like I pointed out, when the company gunsmith says that all 10 mm Dent their cases and even refused to look at the gun, that shows a whole lot about what they call a professional. All they had to do is test the extractor on mine and they could have fixed the problem, but I guess in their eyes I'm qualified as a gunsmith now since I fixed mine better than they did. LOL
