Just curious here, but how many who arent fans, or say no, took the time to learn to shoot the dots, so you don't have to think about shooting with them, and then still decided against them?
Quickly acquiring the dot on the draw took A LOT of practice on my own. After over a decade of carrying Glocks, I never realized they present muzzle pointed up for me on the draw (not a problem for point shooting up close but made finding the dot hard).
For me, it wasn't just the Glocks that felt like they were presenting "muzzle up", its all of them, as that's how I always presented the guns, with the muzzle slightly up, and with front sight focus. Basically putting the front of the gun on the target as an index as it comes up, with my focus on the front sight, and the sights rock into "fine" alignment when the gun presents.
I shoot several guns with different grip angles and never had an issue going back and forth between them and having a problem shooting with them. Glocks, SIG's, Beretta's, S&W's, etc. The difference is usually very slight anyway and if you're accustomed to shooting them all, your brain already knows the guns, and makes the adjustments without you having to think about it. And that goes for aimed fire or point shooting.
Once I realized that shooting the dots is more of a "point shooting" presentation (which, if you think about it, is "target focus"), things went a lot easier, and I believe if you are a point shooter, its going to be a shorter transition for you, than someone who doesn't.
One thing Im seeing more and more shooting with the dots now too is, Im losing the "muzzle up" presentations, even with the irons, and my irons are pretty much lined up on presentation. You might say things are sorta starting to merge and "coming together".
