Speed strips are what I carry. I would not say it is my preferred method of reloading. But strips unobtrusive and easier to carry.
That’s my approach. At the range it’s just two at a time from slip-top boxes. Carrying speedloaders and moonclips is a nuisance to me. Moonclips are unquestionably the easiest and quickest to use, but my experience has been they can easily be bent and damaged when carried in a pocket.
