Get back to me when you have the answers.
How many pounds of pressure are required to fire a standard Glock?
Trigger pull for the Glock is 5.5 pounds. However, I found an article that said Glock measures from the tip of the trigger. When they put the scale in the middle of the trigger in the article it measured 8 pounds.
How man pounds of pressure are required to fire a typical revolver, DA? Haven't found any data on that yet, but since most of the trigger scales only go up to 12 pounds, so I'd say not more then that. My best guess? Around 10 pounds.
How many pounds of pressure are required to fire a typical 1911?
Around 4.5 to 5 pounds.
From the same article that measured the Glock trigger pull, I read it a little more closely and it stated that typical DA revolver pull is 12 to 14 pounds.
Does that sound about right?
Here's a link to the article.

The Glock standard trigger pull is 5.5 pounds, though I believe that New York Police use a different connector spring requiring 8 pounds. There's also a NY-2 pull that runs around 12 pounds. Tricked trigger pulls are often around 3.5 pounds. It's a 2 stage pull with a well-defined boundary between the take-up and release portion of the pull.
From what I've read, revolvers use a pull around 11-14 pounds in double-action.
Trigger pull on the typical 1911 is harder to pin down. I've read of typical out-of-the-box pulls of 4-5 pounds, and at least one source speaks of a "GI" pull of 6 pounds. Competition triggers are around 3.5-4 pounds.
The pressure required for the Glock is not much different from a typical semi-auto. The amount of travel required for the first shot, however, is considerably longer. What makes the Glock unique is that the trigger need not be fully released for follow-on shots; if it's not fully released, the trigger distance required for such shots is much shorter than for the initial shot.
