For those that carry revolvers as their concealed carry firearm, reloads require more concentration than semi-autos. Whether the choice is a speedloader designed specifically for the cylinder, loose rounds from a pouch or a stripper clip-like reload, getting fresh rounds into your wheelgun takes some practice.
The Bianchi Speed Strip holds six rounds and takes a little more dexterity to reload, but lies flat in a pocket for greater concealment. It's a classic tradeoff that pits ease of use against ease of cover. While classic speedloaders like the Comp I from Safariland reload your revolver at the push of a button, the round loader (essentially the same diameter as the cylinder in your revolver) is much harder to hide in a pocket than the speed strip.
With practice (and you should be practicing your revolver reloads), though, the disparity between the strip and the traditional reloader can be overcome. For many revolvers, the speed strip works faster, as the speedloader has to be manipulated around grips or cylinder latches, and all five rounds need to line up perfectly to insert the loader. For the Speed Strip, one or two rounds at a time can be rapidly peeled off the strip until the revolver is charged. It's all a matter of practice, and with copious amounts getting your revolver back in the fight can be achieved quickly.
