Unsupported, I shoot a plastic pistol with a mediocre trigger best. My (GFs) Gold Cup feels thin and top heavy and I have to hold my mouth just so and wait for the trigger to break to be in the same neighborhood in accuracy. If I wanna bust a coke can unsupported at 30-40 yards, I will take my G21SF any day and twice on Sunday. Double that if I want to hit a moving target and/or shoot quickly. Part of it is maybe the big grip, and part is the predictable trigger that "breaks" on the way to firing. But for w/e reason, the closer I get to the break and the tighter I grip the gun, the steadier my sights gets and opposite is true for the 1911 - With 1911, I feel like I need to relax more and more and wait an eternity as the trigger is about to break to keep the sights still. I have no problem following thru and holding on target with the spongy Glock trigger. There's no flinch in my game - with the Glock, anyhow; at least not until round 100-something... and the tight grip I'm sure helps. So with the Glock, I don't need surprise break. Bracing for the recoil and aiming and following thru and breaking the trigger are all one and the same.
If I was hunting from a rested blind, I'd give 1911 a notch up. This is where the trigger would be better for me, not to mention the sights.
*Edit: I had the same problem with my Stoeger Cougar, only much worse than with a 1911. Probably cuz the grip angle is even straighter and the trigger at least double the weight. What happens is I could hold the sights still. I could break the trigger without jerking it. But I found it quite a struggle to do both at the same time. I gave that gun to a good friend.
