Hello all I have been doing research now for the past 4-5 months on a XDM purchase. I am set on a .40 cal. full frame (hands to big for the compact). My problem lies in which barrel lenth to get. I will be "CARRING" it and to also be a "RANGE" gun. Hoping that I will never have to use it for personal protection but just to be safe. I am trying to decide between the 3.8 and the 4.5 barel. There is no store in my srea that has the 3.8 to rent. I am hoping for some feedback in how the two differ from eachother on both performance and acuracy. ANY help in this sit. would be greatly appreciated. Thank you to all those who help in advance!!!
