Just my two cents on revolver rigs... I've carried wheelies for many years and have tried way too much leather before finding stuff that works.
As far as speedloaders go, you have two options, belt or jacket pocket carry.
belt carry, decent designs are:
Galco A35 split six holder
Cunningham Leather over the belt speedloader pouch
Del Fatti SLC or speedloader pouch (splits cartridges astride and atop the belt)
Andrews wrap-around pouch is also a good one.
Rosen makes a speedloader pouch that ain't half bad either, but is pricey.
consider stashing a speed strip somewhere as well. They lie flat and fit almost anywhere (great for painter jeans pocket or jeans mini-pocket, also fits the change pocket inside of jacket pockets in well made coat).
Good leather for revolvers can be had:
Tucker Texas Heritage IWB (but extremely comfy for such a design)
Alessi Belt Slide Scabbard
Bell Charter Oak makes a complete series of belt slides, cross-draws, and other snub revolver holsters from the Chic Gaylord inspired models at very fair prices.
Don Hume also mjakes a decent, and economical OWB for K-frames.
DeSantis Speed Scabbard is also a decent, mass-produced design.
If you wanted an entire rig that matched, consider Wild BIll's Concealment. he was running a special on double-ply belt, double speedloader pouch, and holster for something to the tune of $119 +S/H. He had 3 or 4 different belt holster options to choose from.
