Hope I'm not out of line here, but I'm 69 with bad eyes and bifocal glasses.
What color are the rear dots.
Try something easy: Cover the rear dots with black electrical tape or equivalent and retry the sight picture. When the front sight stands out with no other dots around it, it may help your problem. The rear dots are distractors from the front dot for many, including me.
Also making the front dot bigger may make it even easier to pick up fast.
I've tried paint on sights and it never lasts long for me. It may be the gun cleaners or holster rub.
