I see nothing at all wrong with 4ager's quest. It certainly would be cool to find a pocket gun that met the baseline criteria.
IDK if the guns exists currently, but then again I tend to stick to a few known platforms.
With that said, I AM a fan of pocket guns. Primarily for second guns, or for when I just don't feel like carrying a gun.
For me, it has always been a J Frame. Normally a 442/642, equipped with CT grips.
4Agers search is definitely a solid topic, and there is much to learn from the experiences of experienced shooters that have posted here.
