Normally when I super-size my tacos, I just end up with heart burn. When High Speed Gear super-sizes their TACOs, you end up with versatile pouches that can handle many of the extended rifle, shotgun, and pistol magazines on the market. They have now introduced extended (deeper) versions of their pistol and rifle TACOs.
The Extended Pistol TACO should be ideal for the 33 round Glock mags, MP5 mags, ASP batons, longer flashlights, and probably even Ruger BX-25 magazines. The HCM TACO should be just the ticket for PMAG 40s and Saiga 12 mags. I currently use PMAG 40s in regular TACOs with good results but the extra depth of these would ease my mind.
