Just my opinion.
While I agree or at least appreciate your thoughts on many subjects we tend to diverge where it comes to guns!
You tend to hang way too much stuff on them and haven't kept up with the rapid advances over the past few years in this martial arts. I'm being this direct because I think your writing influences lots of people and as such you should keep current in this field since you write a lot about it!
A shotgun set up like this removes several of the advantages one seeks from the shotgun while weighing it down with several disadvantages not native to the breed.
A shotgun should be light and fast for close in work and not weighed down with lots of extras!
Speed Feed is fine, but no longer manufactured last time I checked! I've got several, but find the reload to be slow compared to other options, but likely good for keeping some slugs on board.
Chokes are fine, but most combat/defense length guns don't have them. Just choose something you can shoot a wide range of loads through!
Easy Loader is for Rem Auto Shotguns.
Some oversized safeties can make the gun less safe! (Specially for those who haven't perfected their handling skills!) Choose carefully!
Tailed followers are fine if quality!
Tac Star isn't traditionally the quality level I want on my guns and there are better choices! If you like rails etc look at Nordic Components.
Slings are likely personal choice , but I tend to make my own for several applications.
I'll be a bit harsh on your sights! Aperture sights (nor ghost rings unless your game is up) do not belong on a shotgun! Pretty much anything else is a better choice! Night sights are an option that is reasonable since it gets dark most places at least 1/2 the time!
A light should be available as needed and easily removable if possible! I've no need for a laser on a shotgun and running against a timer says it slows most down!
Bipod? No way no how! Extra weight to slow you down and take away from what a shotgun does!
Side saddle is OK, but 8 rounds it too heavy/cumbersome!
Butt cuff is fine, but can't be used with Speed Feed Stock specified above. Oh a neoprene one will last much much longer than an elastic one.
Bayonet and adapter once again added weight! My military shotgun has factory set up, but I'd never add one! Shotguns shorter is better hanging stuff off the end of the barrel neutralizes any advantages!
Slings on shotguns are controversial, but I like them. Mine are quite, comfortable and get used a lot!
To improve the compactness of this style of weapon buy an 870 PGO category weapon/other and built it up as a Shockwave with a 14" barrel! It's close range devastating firepower exactly as this style of weapon was designed to be!
