From an historical point of view, I can remember when the wonder-nines first hit the market, excluding the pre-existing Browning HP, everybody had to have one. In reality, police do need high capacity pistols on occasion. One need only study the 1970 Newhall incident to see how that tragedy changed police training and may have been instrumental in the wholesale transition to the autoloader.

I use both a Model 36 and a Kahr P9 for EDC but I prefer to carry a Glock 19 or my Browning HP when going to retail stores. You need to get the job done with what's in the gun. If you must reload, you're probably in very serious trouble. Look up the Sgt. James O'Sullivan shooting at a lower Manhattan (NY) Radio Shack to see what happens when a Model 36 is deployed against multiple armed robbers.
