I converted to dots in 2020, initially because I wasn't able to see the front sights as well as I used to. Been shooting them for competition and in training since, probably around 3,500 rounds to date through four optics. My last class was with Tim Herron in February, a two-day action pistol oriented session with 800+ rounds with my Glock 19 Gen 5 MOS and HS507c. Shoot a Glock 34 Gen 5 MOS with another 507c in USPSA, and until recently have a P365X with a HS 407k, which I just sold to buy a EPS Carry, shortly.
I believe there are at least three very significant advantages to MRDS on a pistol.
1) If you are at an age where focusing on the front sight is problematic, seeing the dot becomes much, much easier. Most MRDS are virtually parallax free these days, meaning as long as your index is good enough to see the dot anywhere in the lens, when you press off the shot, the round will land where the dot is pointing.
2) All shooting is done with target focal plane. You are not going back and forth from near to far focus. Shooting with a dot focus makes shot calling faster. You can see, really see, where your round would land as soon as you break the shot. You don't need to see the holes. If you see an Alpha and a Charlie using the sight picture, then you know to shoot a make up shot.
3) Using a dot will make you a better shooter, and will carry over to iron sights. Incorporating the dot in Dry Practice has cleaned up my index and trigger control tremendously. I think this is an under appreciated benefit of MRDS. The sight is still wobbling around, just as before, it's that now you can see exactly where the dot is at the shot break. With this info, you can work on your grip and trigger control so that the shot breaks when the dot is on target.
Disadvantages of a dot include the learning curve, the added complexity of the various mounting systems, potential failure, battery life, and cost. The learning curve can be mitigated through training and dry practice. The physical aspects have gotten much, much better the last 2-3 years, to where I'm personally comfortable carrying with a dot and BUIS, every day. I mean, everybody weighs this differently and makes their own decision. You can absolutely do good work with iron sights, for sure, and if they work better for you, I'd keep doing that.
