I like .380s for two different reasons - - -
Historical/Esthetic - - Back in the day, these were the "magnum" pocket pistols. In a time when European police were mostly armed with pistols chambered for the 7.65 Browning (.32 ACP,) most of the same platforms could be had in .380 ACP. This was considered "needlessly brutal" and "difficult to control" by many.
But, if you were serious about personal defense and needed to conceal a pistol, the 1908 Colt Pocket, the Savage double stack, and the 1910 Browning design were pretty much
IT. A little later, the sleek Walther DAs and Remington Model 51 enhanced "the Pocket Pistol as an Art Form" image. Those were the glory days of the .380.
Today, though, those beautiful, classic designs are just flat obsolete. Advances in the state of the art render the old designs oversized and overweight - - Needlessly big and 'WAY too heavy for their power. You can dispose 9x19mm power in a smaller, lighter pistol, and, if you still want a .380, you can get downright TINY.
Lest I seem disdainful of the old classics, I mention that I have a 1966 vintage PPK which is NOT for sale. I also have an ancient Colt 1908 in my desk - - Little remaining finish, but mechanically perfect and frighteningly accurate.
Practical, everyday, concealed carry -- Some of the current crop of .380s are smaller and lighter than some older design .25 pistols I've owned. I still don't consider the .380 a first line combat proposition, but, as they say, it beats a sharp stick or a stern scolding.
I have a P3AT in my side pocket as I write this, and it is fairly "forgettable," which is a fine attribute for a pocket pistol to have.
For the future -- I'd love to see the old Colt 1908 updated: A trimmed down, polymer receiver with shortened barrel and slide mounting low, clearly defined sights. Perhaps 5+1 or 6+1 capacity, around 13 ounces in weight. Keep the concealed hammer, grip safety and the same size thumb safety. Flat, light, short, large enough to shoot well - - Perhaps the idea hideout piece. Hey, I can dream, can't I?
Best,
Johnny
