This thing went through quite a few iterations but it ultimately landed here:

The biggest things I learned from this shotgun were that I liked a 12" LoP stock, and the Vang Comp VCS treatment and Big Dome safety were mandatory items for me.
I like the shotgun a lot, but i'm kind of in to having duplicates right now and I decided I wanted to 'start over' with an 870P and get specifically what I wanted from the get go.
I ordered a brand new 870P with rifle sights and factory +2 extension. Before I even shot it I sent the barrel to Vang Comp for their VCS treatment. While in transit they got a handful of factory Remington barrels with the rare "DEA" XS sights. More commonly found on factory 14" SBS barrels. I worked it out with Vang Comp and I got one of those DEA barrels in place of my factory barrel.
Added the VC big dome safety, steel follower, and +2 extension and it was starting to feel like home. Yesterday my Magpul stock and forend came in and wow, for how unattractive this stock is it sure is comfortable.

Out at the range I got slugs dialed in at 50 and 100yds, and patterned some Federal LE127 00 9-pellet buckshot at 25yds

This gun doesn't disappoint. I've got a spare vtac sling on it at home, but I plan on ordering a BFG sling and ultimately an inforce WML for the handguard.
Has anyone ever tried putting an Inforce WML on the bottom of the MOE handguard?
