I saw this system in action at the Rocky Mountain 3 Gun match. I was teamed with the FN Team, Safariland Vice President, and owner of Kodiak Precision. All used this system to trade out various holsters and magazines depending on the stage requirements. I purchased the system shortly after that match. I used the system at the USPSA Area 2 Match and was completely satisfied. I am converting all my platforms to this system.
Pros: Very Flexible, Works on Many Platforms
Cons: Attaching can require manual dexterity
