Just got mine in the mail. They are a teensy bit loose-fitting for .45acp, but some hot water and snapcaps fixed that up right away.
After an hour of walking around the house practicing with them I took them out for some live action. They do work well. They are a lot easier for me to carry than a round speedloader or moonclips, and fit the watchpocket of my jeans just like any other speedstrip.
stay safe.
