Thank you for the reply. I have definitely cleaned the crap out of it. I pulled out the the magnifier glasses with bright LED lights and just can’t see anything. A friend brought his TS over but the barrels aren’t exactly the same. Either way I have an RMA and I’m shipping it back to CZ USA on Monday. I’ve spent two weeks trying to figure it out. Might as well get it to them and hopefully figure out what’s up and I’m really wanting to know if I did something or is it a defect. Just can’t imagine that my ammo which is only 5 points over USPSA Limited Major power factor should cause this. If that’s the case this is not the gun for me. I need to be able to shoot ammo that’s at power factor plus 10. As well around 10K a year if I shoot a lot. Thinking I should have just saved more and got an Edge. Thank you for you response again. I’ll repost when I get it back.
