I had an issue with mine when I bought it, one of my genius buddies racked the slide with the safety half on :. I would take the Right Grip Panel Off and see if the spring in there has come loose. All I had to do on mine is stick it back in place and I haven't had an issue since.

I would post pics but my Bersa is currently sitting in my Mom's desk drawer .

Hope this helps,

Im new, but im gonna say a spring somewhere.

All I have to say is thank you brifol6111 for helping me out with my problem. My gun is fixed and gonna go back to the range tomorrow to blast the rest of my rounds due to my little problem.

There should be a "c" clip holding the hammer bar in place. They have been known to break. You can get them from Bersa or probably find one to fit at the local hardware store.

If the e-clip is missing you can find a 2mm replacement at many hobby stores. Also make sure that the flat washer is still in place.

I just finished fixing mine. I tried all the listed fixes but no dice. I bought the book suggested by Jack at American Gunsmithing Institute since AGI didn't have a video for the Bersa:
Wood, J. B. (1999-12-01). The Gun Digest Book of Firearms Assembly/Disassembly Part I - Automatic Pistols (Pt. 1) (Kindle Location 345). Krause Publications. Kindle Edition.

The model in it was older and didn't have the C-clip and washer holding the trigger bar. After many assemblies/re-assemblies I finally figured out that the ejector stabilizer pin was protruding under the trigger gar and binding it. I drifted it flush, reassembled and it works like new! Hope this helps!
