Where can I get a pistol caliber double stack magazine holder that mounts to a picatinny rail?

Maybe MagSight by Optimus Arms.

That is what I want. Don't need the sights though.

The manufacturer "Full Conceal" went bankrupt. Optimus Arms is just the retailer. Their website looks fishy and there are no online orders, have to call.

The Optimus Arms website gets a 38.2 out of 100 rating for trustworthiness.

On the home page scroll down to Shop by Category and click on Accessories. You can place what you want in your cart from the View Product page. Worked for me, just didn’t place the order.

Seems like that would add a lot of weight to the front of the gun. Could you use a mag coupler instead?

The KelTec sub2000 clicks seems to have several solutions.

Sure, Got one in my cart then could not check out because it said I have to call. That's when I checked the website using a tool another moderator used the other day and got a failed result.

It's for storage, not for usage. An S2K isn't beneficial folded with a 32 hanging out of the grip.

Yes, and the link goes to the original part mentioned in post two that I cannot find a source for so I think I will make something and get rich.

It's pretty cool people actually try to help someone with a problem they don't have themselves even when they don't agree what the problem is if a problem exists. I wish the rest of the world worked like that. Thanks y'all, I will keep looking and thinking.

I am in the process of having a custom part 3D printed. I found an example I like on thingverse and will be having jawstec make the two major parts out of MJF Nylon 12. I will use a couple parts off a QD Picatinny bi-pod mount to finish it off.

3D printed part came in ... in grey. I have it painted and ready to assemble for show and tell but just haven't had the time yet.

Got everything ready to assemble and realized I made an error with my order so now I have to get a $2.31 part and pay $10 to have it shipped. Oh well, that's what I get for not paying attention.

Here is the progress so far.

Got the last piece printed and the hardware. Probably need to find a little stronger spring.
