I have never used these (http://www.5starfirearms.com/Speed-Loading-s/106.htm), but they look like good quality kit. Maybe another member has experience with them. HKS & Safariland is all I've used. Between the two, never had problems with either. HKS seemed more durable, but slower than HKS which was just push with no need to turn (or recall which way to turn). That said, I had plenty of drops onto a concrete range with the Safariland & they never had an issue, so maybe the durability concern was unfounded. For ME, Safariland definitely faster/easier.
