And that's a slow steady pull on the trigger, not a sharp thwack with a hammer.

you could actually upscale this if you wanted to go larger with it as well...

but for referance a 3/4" valve like this would take 44lbs of force to open if it had 100psi pressure... and a 1/2" would be 19.6lbs with 100 psi...an 1/8" would take 1.2lbs with 100psi...and this one at 100psi takes 4.9lbs per 100psi....

Which is why I've only ever seen a SINGLE 92FS at a pistol match. Everything else is a Glock or a 1911 (vast majority). Though there are a few who use CZ's....

You guys are forgeting that it wouldn't be hard to make a trigger that would act on the button directly(no hammer needed), and because of leverage divide the pull amount by the leverage ratio, you could easily be looking at a pull rate of 6lbs or less....

or use a slightly heavier hammer to increase inertia....
