Safariland made/makes pouches that are designed to fit around your pants belt, the loader loads from the top and straddles your belt. The design works better for six-shot loaders than for five-shot but either works reasonably well. OpticsPlanet.com carries an extensive selection of Safariland gear andy you ought to be able to find them on that site, just make sure the pouch is designed to fit on a 1 3/4" belt.
I used them for a while but have gone to a Shoemaker six round ammo pouch for a better fit on my body.
