I just got my Shield 9mm 1.0 back from my son. I'd loaned it out to him as his carry gun was in the shop. After trying the trigger again after a month or so, I'm again amazed that so many people are unsatisfied with the trigger on the 1.0. It really isn't bad at all, especially for the type of gun. I wouldn't spend a dime on improvements to the trigger or find it as a reason to buy another version. But buy whatever floats your boat. It's nice to have so many choices.
