I really like my new Bersa Thunder 380 (Nickel-plated). I would like to get it fine-tuned, with crisp, light trigger pull, maybe no magazine disconnect, and polished internal workings. Maybe even have some of the words on the side smoothed over to non-existence. Maybe refinished in Nickel- Boron parts! Does anyone know of a competent gunsmith that works on Bersa Thunder Customizing?
I've learned that Pro-Mags aren't nearly as reliable as Mec-Gar magazines, after multiple interchanges between them. I love how accurate I am, compared to my Sig P250.
The pistol has been very reliable with lighter reloads, while still operating with full power 380's.
That double action trigger pull is a bit of gritty, hard pulling, and long. The sights are a bit rudimentary...
It seems to work well with steel Wolf, or WPA, as well as my cast reloads. Are there other springs available for light loads? Is there an extended barrel available for threaded?
Is it hard to pull the standard barr
will the barrel,,come out easily if the pin is knocked out?
My 8 round Mec-Gar magaines work like a dream, better than original, and far better than the Pro-Mag ones I bought.
Anyone have specific ammo's to stay away from? Mine uses Wolf and Hornady Critical Defense with ease.
Will be looking for a hip holster (leather) outside the waist band, with a cover, or at least a snap to hold it securely. Any suggestions?
I own a P3AT and a Bodyguard 380, but find them more finicky, and harder to be accurate with, so small, tilting barrel.
Is there a lighter barrel spring for shooting lighter loads?
Does anyone find using a gun scrubber does a pretty good job of action cleaning?
What points are crucial in lubing, after the cleanup?
Can PPK magazines be used in the Bersa Thurder 380?
Can the slide, barrel, and magazines be swapped out to make it a good 22 LR?

I have done trigger jobs on several 380 thunders. My basic workflow is . . . disassemble lower rearward of trigger and magazine catch . . . I use Flitz polish and high speed cotton wheel on die grinder to mirror polish:: #33 hammer strike surface, hammer sear surfaces and hammer pin hole side surfaces, #36 cocking piece sear engagement surface, #28 disconnector inside surface and all other bearing surfaces, #1 the slide middle bearing surface where it contacts the hammer front to back, #35 hammer spring reduce OAL of spring by one coil and grind OD of spring down by 8.2%, #60 barrel mirror polish feed ramp and chamber throat, #1 frame polish bearing surfaces where it contacts #28 disconnector. This procedure smooths up the trigger, removes grit at sear disengagement, reduces double action trigger pull, reduces single action trigger pull. Reduces slide cocking force. Does not result in excessive slide bump. (recoil spring is not changed)

I would like to get you to do your work on a Bersa 380 Thunder Plus (as soon as I can find one to buy). Ever since Bersa changed import distributors I haven't been able to find a Plus. I am a wounded veteran (73yo) and with arthritis in my hands and the strong trigger pull is too heavy. If you could send me your contact information in a DM if you are interested in doing it, I would appreciate it! I had also thought about getting the hammer changed to the smaller hammer from the CC model. I don't know if this can be done. If you could include a rough estimation of the price that would be great as well. Thank you for your time,
Kajunman

I'm trying to do the same, what do the #s you're referencing go to?
