"Tactical" is like the ads announcing "New and Improved" whatever, utterly meaningless.
As for that Disco 870....
A gunsmith who has done work for me for more than 20 years, had a yen for a Pimp Pistol back around the time Afros and leisure suits were in vogue.
He took a Lightweight Commander in 45ACP and shortened the frame and magazine by one rounds' worth, preceding the Officer's Model by a decade or two.
A little goldplating on small parts like the trigger,bushing,mag latch,hammer, safety,etc, set off the lustrous blue of the slide and frame.
One grip panel was Mother of Pearl, the other clear plexiglass so one could count cartridges left in the shortened,gold plated magazine through the slot cut for just that purpose.
This was the most garish handgun seen this side of Hopalong Cassidy's silver sixguns. It also shot like a house afire, was utterly reliable and had a sweet trigger from all that gold plating filling up all the little irregularities in the base metal.Beauty is as beauty does.
TTBOMK, he still carries it daily.
