380 versus 9mm (questions)

[Shoots4Fun]

I have multiple questions and I’ll try to put them as succinctly as possible.
Background: I have a Bersa 380 which I enjoy shooting a lot. Almost everyone I take shooting loves it too. I sometimes carry it, but mostly just target shoot with it at the range. I have some ammo stashed away, but have gotten so frustrated with the availability of the 380 ammo for it recently, that I find myself shooting it less. But, it shoots so smooth and easy, that I want to shoot it more. My only real handgun comparison is my experience with my G27 which is much snappier and more powerful of course. Different in every way.

My next purchase will be a full size 9mm. I’m working to save up for one, but have gotten so frustrated with the 380 ammo availability that I have considered accelerating my purchase by selling the beloved Bersa.

Question: I have read a lot about the stopping power of the 380 versus 9mm, so my question isn’t so much about that. I know the 9mm is better, to varying degrees, for stopping power and personal protection. What are people’s opinions and experience here with the 9mm and 380? What about shooting a 9mm handgun compared to a 380? I know the handguns will vary in their shooting and recoil based on their style and manufacturer, but is there a general answer such as the 9mm is more similar to the 380 or more like the 40 cal?

The 380 ammo seems to be a very popular caliber for the many pocket pistols and back-up pistols. I know I’m not the only one looking for it constantly. Does anyone expect that production for this will ever be ramped up to catch up with demand or will the standard 9mm production always take precedence?

Any advice or insight would be appreciated…
