The first gen lcp has been good to me. Long trigger, and low sights but reliable, tiny and accurate. A piece of bicycle inner tube on the grip and your in business. I haven’t shot the most recent version of the lcp but I think I would prefer it for the taller sights and better ergonomics. Also I’m sure the trigger is easier to manage in a hurry, but I also like the long pull of the first gen because I feel like it adds some safety to a gun that has no manual thumb safety and may be carried loosely in a pocket or soft pocket holster unlike a glock or something where you really need a good trigger blocking holster if you have a round chambered.
The sccy is kind of the same in regards to it’s long trigger pull, but is easier to manage in a hurry vs the 1st gen lcp, due to the better sights and just because it has a more hand filling grip and more natural distance to reach and fully pull the trigger (in my opinion anyway). I haven’t shot one in 380 but have in 9mm. They are actually really good guns for the money. The first so many they produced were plagued with problems, but they were all easily solved and very well understood issues, so that when they fixed them, they actually fixed them! It’s my understanding that all of their new guns are expected to be reliable and of good quality.
The sccy is a bit bulky, kind of a square grip, and if you get one, I would recommend you get it without the thumb safety because it really does get in the way when racking the slide and it’s easy to unintentionally reactivate during a reload. But overall I think they are pretty good guns.
I suspect you can get a brand new gen 2 lcp and a brand new no issues sccy for about $200 each these days. And you’d likely be happy with either. Just depends on how small you want to go, what you like the feel of, how you want to carry it, if you want a bit more magazine capacity, and some other factors I’m sure.
I don’t know anything about the Pico.
