I have a polymer frame CZ TT 45. It is not distributed by CZ USA. In fact, it is identical to an EAA Witness. I have owned this firearm for almost 10 years, and it has spend most of it's life in a drawer. It has a bad problem with jamming, and I need to get it fixed. Do you have any recommendations for a gunsmith? I have cleaned it meticulously, I have oiled it, I have removed the oil, I have blown any dirt/debris out of it, and refuses cycle through 3 rounds reliably. I have even polished the feed ramp. I really like shooting this gun, and I would like to make it function reliably.

Thanks.
