What is physical difference between a 3.5 and a 5 pound Glock connector? Holding them both in my hand, I can not see a difference. Thanks in advance for your reposnse.

There is a slight difference on the angle at the front.

Yes, as stated, it is the angle. The 3.5 pushes the trigger bar down more gently resulting in a lighter weight trigger pull. The 5, with a more abrupt angle yields a heavier trigger weight but often feels less "mushy" than a 3.5.

It's subtle.

Here's a side-by-side comparison.

Look at the lines next to each connector and see how they match the slope of the connector ramp.
