In 1975 my goal was to be either a cop or a firefighter. Whoever hired me first was the way I was going to go. I started to take tests and also started to pass a few. One PD test I passed had only one opening at the time and naturally, and rightly, the job went to a Veteran. However, I actually did okay too and the department suggested that I should become a reserve. So I did. Went through the reserve academy and started to do my field training. The department issued the Model 66 and I was equipped with a Model 19. At that time, the officers were required to carry .38 Special 158 grain SWC-HP as their first six and were allowed to carry 125 grain SJHP .357 for their 12 rounds of back-up ammo. (In speed strips!) That went on for 6 months and then I was offered a job as a firefighter in the same city.
Time went on and I still had plenty of friends on the PD and they kept me up to date on what was happening. The big thing was in 1976 they were allowed to ditch the .38 Special ammunition and go to all .357, and use speed loaders too.
I typed all that to say this, when they used the .357 125 grain SJHP to subdue suspects, it was devastating. No ifs ands or buts. One shot stops were common place and more often than not, fatal.
Of course they were no different and as automatics became fashionable the wheel guns went the way of the Dodo. Now they issue the Glock 21 and Glock 22 and allow various other officer purchased platforms with the 1911 being the preferred choice.
And to digress, the times I've seen the .45ACP used, it's every bit as effective in subduing criminals as the .357, YMMV
