I bought this for my Xdm .40 its snug on the magazines they don''t fall out when you flip it upside down and shake it. The rubber on the inside always helps with holding it in place and with a simple twist forward or backward you can take it right off your hip (unlike the itac where you have to fight it off). The only thing i don''t like about it is itac mag holders are adjustable with an allen wrench so if it wears out you just make it tighter the fobus uses arched plastic that could possibly wear out with time.

Excellent quality. Four stars because I prefer softer, less rigid material for everyday wear.
