My rig from Milt Sparks came with their speed strip pouch - not featured on their web site: https://www.miltsparks.com/. It is designed for the Bianchi Speed Strip: https://safariland.com/products/speed-strips-pair-10851. The Bianchi holds 6 38/357 rounds. The Milt Sparks pouch holds the speed strip vertically, taking less room on the belt.
I just received a Most Versatile Ammo Pouch from Simply Rugged: https://www.simplyrugged.com/ecommer...170&parent=671. This pouch uses the Tuff Quickstrips: https://tuffproducts.com/7002-quickstrips-black-2-set/. The Quickstrips have room for 8 rounds - or 6 rounds with 2 empty slots to ease manipulation. The Simply Rugged does occupy more room on the belt. Delivery was quick - about 3 weeks. Quality seems excellent.
Options are good!
