I used to enjoy having the 1911/glock discussion ( I am staunch 1911 by the way). In training LEO for I service it was amazing to me how many do no practicing or skills tests on their own unless forced to and provided ammo from the department. It wasn't always this way. They took pride in their weapon and treated it with care and learned to use it efficiently. Unfortunately a lot of that has gone by the wayside. Sidearms never come out of the holster unles entering the jail or after shift is over.
Had one sheriff tell me that a 1911 cocked and locked looked too "Aggressive". As in those wearing it were looking for a fight. He didn't like it when I told him that every glock that was carried chambered was also "Cocked and locked" you just couldn't see it. That went over like a lead balloon. Now there is a trend of officers being forced to carry an open chamber on duty in their weapon. This trend is meant to force the officer to make a conscious decision to use his weapon and put a stepping stone in front of him using it without thought. THis has also resulted in several job related injuries and fatalities. After a good amount of data, thankfully this is going by the wayside.
Another point to make is that most departments are Monkey see, monkey do. One one sidearm is allowed for the entire department. That means once the sheriff or chief decides on a weapon they all have to carry it. Good or bad. I feel like this is a horrible precident to set but hey, they are free to run things anyway they feel appropriate. I appreciate a glock, they are damn near indestructible. Handle little care with ease and have a solid reliability. However choosing one because it is less maintenance is foolish at best. I have always felt like officers should carry whatever they are comfortable with and can qualify with. That gives them some personal pride in their weapon. I know several LEOs that carry revolvers on the job to this day. The thing is I wouldn't point a gun at any of them. Those guys feel safe with their wheel guns and most are extremely proficient with them. Certainly as good as the average auto shooter. Just some thoughts.
