While there is a physical difference, youre forgetting the ability of the human body and brain to adapt, and adjust, which it does, automatically, without thought, especially if its had the opportunity to do so in use and practice.
The only people I see bitching about the difference, are those who dont have enough experience with the different guns, to know that it doesn't matter, once your brain knows the gun.
I regularly shoot Glocks, 1911's, Berettas, SIG's, a few other autos, and a bunch of different revolvers, and do so interchangeably, at will, with no trouble at all. And if I can do it, you certainly can.
I point shoot with all of them too, and regardless which one is in my hand at the moment, they all point where Im looking, and the rounds go where Im looking when I shoot.
If you track the sights while you shoot, grip angle is meaningless, even with a gun you never handled before.
Anyone shooting a gun with a lower bore axis, that has a grip that allows for a higher hold on it, understands that advantage, and regualrly shooting guns of both types, Ive yet to notice that the trigger is a reach or problem with any of them.
If this grip angle thing is such an issue for you, I would highly suggest, you get the gun that you say is such a problem and spend some quality time with it. Do that, and I can pretty much guarantee, in short order, you will have a whole different outlook on things.
It still probably wont be your favorite (you never know though
), you may not shoot it better than something else, but it will stop the whining and silly BS, about things that dont matter.
If you really want to do yourself a favor too, get a decent DA revolver, and learn to shoot it DAO. That will do wonders for ALL of your shooting, and addresses the other worry so many seem to have, the trigger.
