It might help to shoot with both eyes open when shooting irons, helps to be consistent. It is very easy, focus on your front sight and simply open the other eye, your brain will pretty much ignore the new information and sight/target picture remain the same. It won't be long before you won't need to close the non dominant eye first.
Next, the beauty of the red dot, is it will be in focus on the target. The target no longer needs to be blurry, as when you focus on the front sight.
As was mentioned do a good solid bench rest and get the dot on target. Once it is there, just have the dot in the window (kind of dumb advice, because if it's not in the window there is no dot...but it's what everyone says ) and place the dot where you want the bullet to go, and keep it there until the shot breaks. While dry firing. practice your presentation for consistency, same grip, same presentation every time. Over time the dot will be there almost every time...and when you get sloppy you will know instinctively what to do to get it right quickly.
IMO best to do one thing at a time...hit your target every time first, then work on presentation and speed....although the first will solidify your grip and help with the second.
It seems to me from talking and reading from others the biggest problem with acclimating to red dots on pistols, is fighting how simple it is. People hear about "finding the dot" and they start thinking it's so much harder than iron sights when it is not. When you stop and think about it, if the shot is on target with the red dot, wouldn't the iron sights have to be aligned also? The red dot does not change where the bullet is going...only the muzzle direction does that...any sight merely assists us in directing the muzzle. With the RX you can cowitness with the irons, present with the irons and you will see the red dot in the window also...the presentation is exactly the same..."finding the dot" is all in our head.
