I agree with the above account, All except the T45UC having a polymer frame. This is incorrect. All Bersas with the exception of the new BP9/40 CC are Aluminum Alloy frames.
Standing corrected (and humbled)...My black matte T45UC (Mini, not Pro) is indeed built with an aluminum alloy frame...and not polymer as I had stated...
I purchased it NIB in Nov 04, and it has been my edc (every day carry) since. The gentleman that I bought it from, had stated that it was a polymer frame, and since it seems pretty light weight (27oz) for a big bore auto, I assumed he told me rightly.....my bad...
I still stand by the fact that it goes bang every time I pull the trigger, and I very much trust it as a SD/CC pistol.
Respectfully,
