The safari lands are awful IMHO. I have two for duty use. I can never see my to get consistent retention across all three mags. Unfortunately, I have not yet found a Kydex or especially something in basket weave, triple mag pouch that is better. On my tac team belt (first spear agh), I run a nylon triple mag pouch that works great.
Very interested in other options, as my new agency does not have leather/basket weave requirement and allows outside carriers, so I am reconfiguring...
Yea the slimline triple was an absolute fail for me. I ended up getting a double and single kydex Comp-tac w/ techlock and running those as a triple.
