I have used the Pitbull Tactical Universal Mag Carrier for the last year and highly recommend it. The Pitbull Tactical UMC allows me to carry inside the waist band for no profile and low profile concealed courses to running sub loads on my duty belt and plate carrier when in high profile conducting CQB courses. I also recommend the Pitbull Tactical UMC to new students who haven’t settled on the exact weapon system they are going to carry yet allowing them to change platforms as they gain more knowledge with out spending more money on multiple magazine carriers.
