We’ve talked about a variety of magazine holders (Friday Favorite: Magazine Holders) including horizontal holders and how to cant your holders.
@Dawn Blue Stone Safety Products in the Beautiful State of Wisconsin has got many very outstanding storage devices to carry extra ammunition and police supplies.
Daily carry is a crossbreed single mag holder. It’s starts off up and down but through the day it usually gets canted to 45-70 degrees (I adjust back to zero throughout the day). It does the job.
I have a very old Galco leather mag holder that works like a charm. Vertical with no cant.
I use the NeoMag magazine holder.
A Leatherman multi-tool case
5.11 jeans. Build in mag pockets
Couple of used DeSantis leather single mag holders. Recently picked up a used Dillon double mag holder I want to try out soon.
I have one in a spare slot on my IFAK ankle holster. The other one closest to hand is a 3-D printed design that drops low in the pocket like a snagmag would. I will probably get a snagmag or do one in kydex once I figure out everything I want it to do.
That is a great grey man approach!

EDC’s - Galco leathers on belt &/or on a shoulder rig.
At the Range Galco’s noted above and MCE 3d printed waste mounted magazine carriers.
My 2 cents. Just make sure your extra mag holders are not flexible like the one looks pictured but extremely rigid in case you need to do a tactical reload.
