This is an excellent point! It is quite applicable today where we have a large number of 9mm pistols readily available to the public. During the late 60s when I began carrying concealed in public, there were few options: the Hi-Power, S&W Model 59 were the most accessible. There were a small few others from the Eastern Bloc that trickled into the West but remained obscure until the mid-80s. Today, I have only four 9mm pistols in my battery. I sold my custom Beretta 92 years ago simply because it was too big to carry. My stainless S&W 659 does only home defense duty because it is too heavy to carry more than an hour. The Glock 19 lives in by BOB. The wife OWNS the original model Kahr. That leaves the Hi-Power. With its svelte curves and long barrel, it is so easy to conceal even without a good holster. With the exception of the Kahr K9, the Hi-Power remains the only 9mm pistol that I would carry concealed despite many other makes and models. Its only disadvantage is its size. One cannot just throw this in a pocket with the wallet, keys, and other things. It is large and long. It is a combat pistol that still services the armed forces of dozens of nations and is a handgun for those such as myself that prefer the cocked and locked mode of operation and the longer sight radius.
