Sorry for your problems Nakanokalronin.
With so many small, quality 9mm pistols on the market I'm not following your logic with saving a buck on an ineffective caliber Bersa that already hasn't worked for you.
I'd suggest you spend a few more shekels and get either a PPS or an HK P2000 SK. A totally reliable handgun with a lifetime warranty...
You know the old saying, "Buy once, cry once".
When it comes to a handgun I might need to save my life or my family's, it's no time to try to get "a deal" IMO.
At any rate best of luck in your endeavor.
