I have read a lot of posts that the XDM 3.8 compared to the 4.5 at shorter ranges (<25 yards) the barrel length does not affect accuracy. Does anyone have any range experience to confirm or deny what I have read elsewhere. I bought the 3.8 because it was a Davidson which gives me a great lifetime warranty and was being sold for the same price as the 4.5. I just want to know if having a lifetime warranty is going to do me any good should my life be cut short due to me not being able to accurately defend myself. I am hesitant to shoot the gun and render it used before I get some confirmation so any bit helps.
