A week ago, I bought a Gen6 G19 COA. That’s the one that comes with the factory-installed Aimpoint COA sight. My eyesight these days is such that I really need bright-looking sights to differentiate them properly, and it’s my hope that an RDS will fix the problem. Either way, this is the first truly ambidextrous Glock I’ve ever owned. Being a southpaw, this makes me happy.

This is my first RDS on a pistol. I have two on carbines and really like them, but I’m a little confused by the one on this Glock. From the factory, the windage seems properly lined up, but I’m a little confused about the elevation. When I line up the iron sights (a little difficult because they’re not suppressor-height, so they sit right at the very bottom of the sight window), the red dot sits right on top if the front sight post, also very low down in the sight window.

Is this how it’s supposed to work? I always imagined that the proper sight picture would put the dot square in the middle of the window, rather than at the bottom. Any suggestions would be welcome.

TAM, I do not think the RDS and regular sights can are co-located where you can line it up together like that. I can do it on the Glock 17 MOS I have but it came with the higher (suppressor level) sights. In your case I would suggest ignoring the iron sights and just keeping the red dot in the center of the scope to sight it in. Practice with the RDS turned off so you can use the iron sights if it is ever necessary, But I doubt you will ever do so other than in practice.

I do not know enough about the RDS to say which are good or bad, but I have a Holosun with a green dot that I find easier to see than the red ones I have used. It also has a solar power charger built in so that the batteries almost cannot go dead. I have been pleased with it so far, and my groups are much tighter when I use the RDS without over thinking it. That took some practice, but I have become a believer that the RDS will improve people's shooting with practice.
