Pocket pistol sounds too generic. How about mouse gun.
My Beretta 21A 25ACP (AKA Bobcat) DA/SA with a condition one (Jeff Cooper) safety and tilting barrel is one of the many Beretta products I like. But some changes/improvements would be nice. A Glock type metal treatment called Tennifer (Austria version) would be nice making it virtually rust proof. I tend to get rust more on this pistol than any other most likely because of it’s placement.
