Depends on what gun you have.

In a Gen 3 - the standard connector is ~5.5lbs. The "-" brings this to 3.5-4lbs.

In a Gen 4, the standard was up over 6lbs, so Glock introduced the "." connector, which brings it down to ~5.5lbs. The "-" will take this to about 4-4.5lbs.

If you have a gen 3, you can use the "dot" connector for a middle ground.

No, I dont think any of the connectors are "unsafe", nor too light. You still get the "shelf" before the trigger breaks regardless of the connector, its not like it turns into a 1911 trigger.

And if you want a smoother pull, its worth a bit of time with a dremel or a lot of time polishing the metal connecting surfaces. You can find some DIY's online, which are not difficult to do.
