Checkout these maintenance posts from "Clampit" Bersa Gunsmithing - Page 3 from the Gunsmithing section of the forum (3rd page). He goes into a lot of assembly/disassembly stuff with videos, IIRC. Good luck. Could it be just a simple clean and oil problem?
Thunder 380 trigger not working correctly
I have a Thunder 380, have about 300 rounds through it. Recently I've noticed that sometimes after it chambers a round while firing it, when I pull the trigger, the firing pin doesn't strike. If I release it half way and then pull it again it then strikes. I cannot rely on it if its doing this. Does anyone have any suggestions or have had the same issue ?

I recently bought a used Thunder 380 with the same issue. After a good cleaning and reassembly I noticed that the trigger drawbar running along the right side below the slide was hanging up. This gun has the Bursa laminated wood grips. I removed the grip to see where the drawbar traveled and noticed rub marks inside of the wood grip along a relief cut made for the drawbar to travel in. A little trimming with a rotary grinder and presto -- no problem. I wonder if the previous owner traded because of that little issue.
Howdy dawgbonz.
Welcome to Bersa Pistol Forum glad to have you with us from the Lone Star State.
I wonder if there are other Bursa Thunder 380 users with the Bursa laminated grips that may have this type of problem. Hopefully after reading this post they will check and let us know.
Anyway welcome on board.

Hey Tony - Glad to be on board. Yep, I am new to the site and new to Bersa. Not a new shooter.
An update to my saga with the grips. We went to the range today and found we did not solve all of the problems but think we located the issue.
First as I stated earlier, the trigger would not reset because the drawbar was rubbing. Today, we found that when shooting in double action mode after releasing the safety, the striker would only dimple the primer but not sufficient to fire. Second pulls did no better. Talked to the guys at the counter (where we bought it) and used different loads... same problem. Started watching exactly when it happened and the movement of the drawbar. Removing the right grip showed contact points again in the relief cut and in a circular cutout that accommodates a linkage point with the drawbar. Will get the rotary grinder out again then make a trip to the woods. It also seems the grip moves slightly -- so making adjustments as needed. This was our first outing with this shooter and my wife put me to shame -- (it's hers). We see why everyone raves about them.

Very late to this unfortunate party, but I experienced a similar issue today at the range. I was able to throw maybe 4-5 rounds down range before I experienced a failure to fire/strike. I figured maybe the pistol was dirty, but now the hammer will not drop or strike whatsoever when the trigger is pulled (it will follow the trigger when initially pulled but it will not complete it’s action, instead I hear a problematic clicking sound at the end of the pull).This is a very new pistol for me, I’ve put maybe 20-30 rounds through it in total, having purchased it last month, so this a bummer. Anyone else experience this issue?
Rasper, Take it apart being very careful with disassemble to watch for any springs small pieces of steel or friction fillings. Examine the hammer spring, do a thorough cleaning, make sure nothing is broken including the firing pin.Very late to this unfortunate party, but I experienced a similar issue today at the range.
