I'm using the equivalent (LW3.5) with the stock trigger spring in my endurance test gun, which is my carry gun. It gives me just a bit over 5# trigger pull which is my threshold. I was talking to vcdgrips after first shooting with the LW3.5 before I got a chance to weigh the pull and expounded on the different ways I might be able to increase the trigger pull because it felt too light.
Like anything else, it's a compromise. There is no getting around this simple rule: The easier a gun is to shoot, the easier it is to shoot accidentally.
