I carry a J-Frame regularly.
In the opposite front pocket I carry a speed strip with 5 rounds.
If I am wearing an untucked shirt, I will also carry a speed strip, also with five rounds, on my strong side in a dump pouch.
I will also oftentimes carry two speed loaders in a coat pocket.
I prefer the HKS over the Safariland ones for the simple reason that when reloading, I am already holding the cylinder steady, and I am already twisting the loader to line up the cartridges. The are much quicker for me.
