Just got finished installing an apex trigger on my dads sw9ve and the weight of the trigger pull still sucks in my opinion. It is better than before but still ay to heavy for my tastes. I tried putting a spring kit in first and see what kind of results it yielded and it was pretty negligible as I don't have a scale to check it. He wasn't satisfied and had me order the trigger and after I got it installed it wouldn't fire. It turns out that the trigger was hitting the frame before it moved the sear block far enough to fire. An hour later after filing and shaping it works. At least when I try to squeeze a round off my hand doesn't start to shake from the effort needed to pull the trigger. Im a S&W guy to the bone, but this one is definitely not my favorite, I hope he likes it cause that's what really matters. Is there anything else that can be done outside of copious amounts of range time to get used to it?
