Funny you wrote that. A while back I let a young hot production shooter mess with an open gun and I actually felt a little guilty....almost like I was introducing him to crack or something equally evil.
After steaming through the plate rack a few times and doing a some impressive bill drills on paper he said he liked his CZ production gun better and thanked me.
I thought that was cool. Odd, but cool. Maybe he was too polite to say that he will wait to get into open until his eyes go bad and he is too slow to reload. i donno.
My eyesight isn't that good any longer, but what I found is that good single visions that allow a decent front sight focus let me to shoot irons pretty well. For the red-dot open guns I use mild progressives for a target focus. So, glasses with a good prescription for shooting can help a lot no matter what type of gun you choose to shoot.
Definitely try a few open guns out if you can. Not everybody takes to their feel. Also, they require more attention and the oddest stuff can make them finicky, which can be frustrating.
I like open, but I really like revolver a lot, too. Been playing with single stack minor lately and doing OK, but when the weather cools down will go back to open.
It is all good.
Hope you find your happy place!
