I own a 4043 and it's my normal carry pistol right now.
Took a little getting used to the DAO trigger as my other 3rd gen Smith is a 1066 and I also have a SAO Browning High Power. I like shooting the 4043 now that i have gotten used to the trigger a LOT. I swapped in a 16lb hammer spring and then spent some time dry firing it to get the feel of the longer DAO trigger. At first with the stock hammer spring I had to take my time or I pulled low but now shoot very well with it. I like the thought of having that consistent pull and a longer more deliberate pull if I find myself in a defensive situation where my adrenalin is really going is not a bad thing.
