I don't think you should be discouraged with this learning curve break-in period. You are going to find a round that not only functions reliably but also hits to point of aim and behaves consistently at long and close range.
One of my favorite YouTube influencers is Stav at "SheEquipsHerself".
Nothing profound there but she and her fine husband have done so much to bring new shooters especially girls into the 2A fold. I found them when researching the Glock 42. So did S&W. That is why they were invited to the factory with other influencers to the launch premier of the BG2.0 last year. Shooting the factory tuned sample it was all wonderful. When they got home with their own copy they started having feeding issues. The husband did a video on it and explained that the problem is with the 2-part feed ramp. We had the same issues with the old Colt 1911 and is the reason some will still only shoot ball ammo.
He showed that he wanted to always use flat point ammo. A lot of people coming from the 40 S&W think that and the people coming from 38 wadcutters think that. Very soon, I expect you will start seeing comments that the 380 is under powered and you should not use hollow points, etc. etc. However, the shoulder of the FP meplat would hit the gap and go awry. I cannot remember if he found a work around.
Polishing should help. Also look at the upper surface of the chamber as the round has to bump/bounce off that to go in fully.
Note: I could not find the video I was talking about on their channel. Sorry.
I did see a lot of Tubes about polishing the internals of that pistol.
Good Luck With This!
