They both are a modified version of the old Colt PocketLite/Mustang.
I'd like to get my hands on a P3-AT. It still offers the highest power density of all the micro guns. 7rds of .380 in 10.7oz (loaded).
I'm not a fan of .380, but there are times I could carry that when I couldn't carry a gun.
The P3AT is what has been in my pocket with Corbon +P since they came out.
Killed coons, armadillo, and used on animals as big as coyotes to dispatch a wounded one.
Every round has made full penetration.
Like others said, it’s not a primary defense weapon, but it’s always on my person when it would be impossible to carry anything else.
