DJ I am left eye right hand too, I am not tooo slow on the first shot though. = the key is head movement. Get your head in place and keep it calm and Present the gun to the eye.
When you make ready = set your head in place and holster the gun { With Out moving your head} - put your hands in the start position and draw the gun to your eye and the target. Use your off eye too when you get the hang of it.
Do the closed eye drill too = point the gun in dry fire close your eyes - open them and see if the gun is still pointed correct. If not practice from the the feet up to make it rite.
Oh & =Moving through doors and such keep from (Ducking) your head to the gun = Keep the head level, like a dancer. and in don't bob you head up and down.
Being a left eye right hand shooter also, I am quite interested in your practice drill. I think I've already been doing some of it but seeing it all spelled out sure helps. Thanks.
BTW, I learned the hard way not to shoot without a dot. I could kick myself for all those unecessary misses. DUH!
The red dot is your friend...don't shoot without him.
