I really like the look of the Redux over the Duckslide because of the 12g in the grip. I only use panel on my 45 grips so I do not mind if the wraps do not fit.
Insert based barrel? Do you mean it will take freak inserts instead of the phantom detents because the detents are good but the freak inserts are best.
I love the overall look and will be happy to see some out there being used. I don't know how many FL boys will buy considering not much SC play out here, but I will be picking one up for sure.
