I was looking on the Fobus website at their Surefire 6P/9P and double stack Glock mag holder. Now according to the Surefire website the 6P is similar to the G2(what I have). So it would make sense to me that the G2 would fit in this holder.
But before I make the purchase I figured I would consult the members of the forum. With my luck the G2 having the polymer style would be a tad too thick for the perfect fit that Fobus usually requires.
