With revolvers you have to allow the trigger to go fully forward before you can fire again, as with some DOA pistols. Glocks and 1911's generally have a short trigger travel and a short reset. With a pistol, there is no way you can reset the trigger between firing the gun and the slide operating, my experience is the same with rifles. What you can do is "miss" the reset by not allowing the trigger to go far enough forward. That being said, every successive shot, the trigger must reset before you can fire another round. On my Glocks especially, I can feel the reset "click" if I try to, I have shot it enough its pretty automatic.
I personally do not care for 2 stage triggers on AR's either, I grew up shooting plain old rifles with single stage triggers, why change now?
My rifle and pistol are tools, I am the weapon.
