Ssshhhh! Don't tell anyone how good the Bersa's are; its hard enough now to find magazines for them.
I have both the 9UC and 45UC. The 9 has been totally trouble free right out of the box. The 45 had some feeding problems initially, but has been getting better as it breaks in. Surprisingly it had less problems with hollow points (Taurus Hex) than with ball (WWB).
