That is a very slick setup, Patrick.
Have you ever had any issues with the rear sight getting bumped and moved in the dovetail?
Holy shit; you, sir, are a genius. I have a Beretta 390 that I chopped up at both ends for a house "dudeshooter". I didn't bother to put any sights on it, as it points just fine for room distance work... and most of the available sight options are expensive/PITA to install/both. But a friend is exploring this topic (shotgun sights) for a close-in pig gun, and I was telling myself I need to get off my butt and put SOME sort of sights on the DudeShooter; which is a 390 bird gun with synthetic furniture that I got NIB for a song. The barrel is cut to 18"+ an RCH, bisecting one of the rib posts just like your photo. And I know a guy with a Bridgeport and dovetail cutters...

Here's the link to find those sights. http://www.xssights.com/Products.aspx?CAT=8271
Comes with 3 different heights in the kit.
We also have the kit for $40.00 that doesn't have a front sight, if you want to use your own fiber optic etc. You'll have to call to order that set because it isn't on our website yet. SG-3001-9

How would one go about getting a big dot front and tritium stripe rear like is offered on some of the handgun sights and how does one deal with getting the right elevation? Should I get a big dot front and non-tritium rear to test for rear sight height then get a tritium rear in the height of my choice or what? I'm liking the idea of the tritium rear to help with indexing in low light.
