Picked up the 590A1 at the end of February. I wanted an upgrade from my old 500, specifically to shoot some slugs at longer distances.

I didn’t get around to shooting it for weeks. I already had Federal Flight Control, but bought more Hornady Black and Critical Defense with the versatite wads, plenty of bird shot to break it in.

We finally caught a free afternoon and took my son with me to burn off some of that young teenage angst. We set up at 50 yards, every shot with the 590 was low. I’m aiming for the neck and hitting the dirt where the pelvis and thighs would be.

I pulled out the 500, loaded a round, put the bead high on the chest and hit.

I jacked the rear sight all the way up, trying to put the top of the post in the center. It’s just not working for me. If I move up to 35 yards, I’m at the belly button. 25 yards were dead center mass.

I think it’s this damn red post. It’s not a dot and it’s throwing me.

I did some measuring and ordered a Marbles 37MR front dovetail thinking it would be slightly shorter. I got it in today,

It’s a lot shorter!

Possibly too short. Thoughts?

I could bring the rear sight all the way down, still might be too high. I’m wondering if I might be better off with this front sight.

It’s technically the same height as the Mossberg factory sight, but if I center on the dot, that should raise my point of impact.

Anyone have a similar problem or use the Meprolight sight?

Why didn't you just mount a red dot on the 500 & throw on a rifled barrel?

Red dots just aren’t my thing.

I have a solar holosun on one of my AR’s. That’s plenty.
