Scarcity Or Non-Existance Of Mossberg 500 410 Saddle Mounts, Shell Holders, Etc

[Get-The-Lead-Out]

Good grief have you ever searched for a Mossberg 500 410 shell holder/carrier not to mention other tactical accessories for it?

I've finally burned myself out after nearly a month on trying to find anything for my 410

Can find gun slings that you slide the shells into but eh with me being in a wheel chair, the gun sling is a big problem that constantly gets caught on things, and so just one of the reasons I want a shell holder for the 410 that mounts to the receiver like how theyre so commonly made for the Mossberg 500 12ga and the 20ga

Any help including direct links to a product would BE SO NICE
