DAA plastic pouches can accomodate STI,CZ,Tanfoglio,glock. You have to just take off the knob pin
and place it to fit the CZ, Tanfoglio mags. Works well for Cz, Tanz if you leave it on STI
spacer..just have to tighten a bit but it holds. I do it coz Im too lazy to put the knobs where they are suppose to.
Besides I switch to STI 1 week, then Cz the following week then Sti..Lol
