Before there were micro-Nines, subcompacts, and whatever, there were truly tiny pistols. The purpose was for extreme deep concealment, situations where being found to be armed could be more than a serious problem.
First and only gun that ever slide bit me, hard!The smallest pistol I’ve ever shot was a Walther PPK/s in 380 ACP. It was actually easy to shoot. I think that would be the smallest I would go. Anything smaller would be uncomfortable for my big hands
