Long shot - source for 870 DM specific parts?

So I’m extremely late to the 870 DM platform but I’m really thinking a 10” 870 DM would be perfect for my needs.

I know these are rare now and mags even more so...

My question is what parts are specific to the 870 DM and any idea where I might try to source them?
 
I would expect the mags & magwell, trigger group to some extent would be it. The mag tube would be neutered I would think but likely the receiver end would just be plugged, there’s probably still a mag tube spring and end cap to secure the end cap/mag tube nut. Most likely will not have shell latches either.
 
I own one. 12.5" is going to be significantly easier, given that you can buy any existing 870DM and drop a barrel on. Any 870 barrel will work on the 870DM - I used a 12.5" Dlask barrel.

The bolt is specific to the gun, and includes some small parts that I would like to have spares of - a screw and washer, plus the tab that push feeds rounds from the magazine into the chamber. The magazine well could likely be retrofitted to an existing gun, but that would require a drill press and a lot of measuring off of an existing gun, and is not likely to be worth the hassle. Otherwise, there is a modified trigger group with an enlarged bolt release, plus a feed ramp that is held in by the front screw from the magwell. The magazine tube is empty, and is effectively blocked by that same front screw.

It's a fantastic gun. I have three six round magazines for it. I'd love 10 rounders, maybe one day. I'm tempted to modify the follower to squeeze an extra round in, as it seems like it would be a very small amount of material to remove.

I recommend it over a standard 870. You can go from an unloaded to fully loaded 870 in about one second flat.

Mine was worked over by Casey at TacOrd, to include some dehorning and then cerakoate, because it is essentially an Express 870, with its standard mediocre blued finish.

Thank you both. Wish I’d gotten into them when they were readily available.

Bradley that’s mighty close to what I have in mind except I’d really like to do a 10” if possible from Dlask or Tac Ord.

Maybe Rem Arms will bring these back to life once they’re up and running.
 
If your looking for parts I’d try Gravel Agency.

PaveHammer, hows the barrel nut lock down if the mag tube is empty. I’ve got a mag fed grizzly and it has the spring and retainer still in the tube to lock the nut and barrel in place. Interesting to hear the specific differences between them and the standard 870’s.

My local gun store has at least 2, no one wants them.

Why?

No extra mags. Thus your DM really is just a regular 870 at that point. zzz

Mags, yeah they’re non existent it seems. I spend hours search but found none. No mags make it a pointless setup.

Contacted RemArms they are considering getting more mags to market but have no intention of making the shotgun again.
 
It's disappointing to hear that the system isn't getting the support it deserves - the mags are rock solid, both in construction and how they feel in the gun, unlike the Mossberg equivalent.

I bought a few spares when I got the gun, the last of which came from SFRC, but it sounds now like they've dried up everywhere. I'll have to keep my ear to the ground to try to find some more to deepen the stock.
