What are the rules/laws on switching calibers on your carry piece here in AL? I have a factory .40 sub compact pistol and just bought a complete 9mm slide and barrel set up for it. Is it legal for me to carry the 9mm set up?

I do not think we have any laws regarding the change of caliber. The think I might look at are the slide and the mags used. All need to be 9mm And the slide needs to fix the new 9mm barrel.
Good luck man.
Also handgun laws.us will have more laws related to Alabama.

Thanks for the link, after reading I think I am good to carry with the swap. Yes everything is 9mm mags, slide and barrel. I wouldn’t even consider carrying a conversion barrel in my .40 slide for reliability reasons.

It’s not about the slide. It’s the serial number stamped/machined into the frame. Switch and swap all you want to.

There is nothing in Alabama carry laws tying a specific gun to your carry permit. I wouldn't carry a highly modified gun for legal reasons but any handgun you own and can conceal is perfectly fine.

No legal requirements for caliber conversions in AL. That being said I would not do it for reliability reasons! (I have a Glock 35 w/ a Lone Wolf 9mm conversion barrel. It is very finicky especially with 115 gr loads.)
