So I recently installed a new apex duty/trigger kit in my 40 shield. Took it to the range and I must say I didn't notice much of a difference. I am in MA where it has a 10lb trigger pull so I was expecting it to be quite a noticeable difference. Even the reset didn't feel much different. After researching a little it seems that some folks keep the factory trigger return spring rather than using the apex spring. Anybody here have this experience? Kind of bummed and I'm out $140. Thanks in advance
