I carry a Bersa Thunder 9 UC Pro in a Fobus paddle hoster OWB with a shirt hanging over it everywhere I go. I 've been carrying since 1970 when I got out of the Army.
I have a Bersa Thunder 9 UC Pro and have around 2,000 rounds thru it. I have never had a failure of any kind with it.
My daughter has one also as her carry pistol. She has never had any failures with her's either.
