The NYPD was notoriously famous for being against everything from automatics down to .357's and even speed loaders. We fought tooth and nail for years for something to place the street cop on even footing to a certain extent with those armed with the infamous Browning HP, which can hold up to 14 rounds. Those autos were the weapon of choice among groups like the BLA, etc. from the 60's to 80's. I even carried one as back up in my early years, but was forced to stop.
We were told every year by our range officers, while re qualifying with our weapons, that new weaponry was always being considered and experimented with all the time. Every excuse was given to us regarding why our 38's were the best under the current circumstances. Most of us didn't buy that.
We lost a number of people back in those days, including a friend of mine, because we were in fact out gunned and had a primitive way of carrying our ammo, which were stacked in pouches on our gun belts. We couldn't even have speed loaders, amazing!
The PD's across the country have many experts within them, who know far better than I do about such things as, guns and equipment, but a number experts who are in the know fall into the dangerous category of knowing what the CORRECT thing to do where arming the police are concerned, but don't do it, because they confuse it with POLITICAL CORRECTNESS.
