Apparently, there is a new (fifth) connector in the Glock world, the "dot" connector. I haven't seen one yet but hopefully will have one in the next few weeks. I've been told it is designed to fall somewhere between the competition "minus" connector and the standard one.
So now there are, from lightest to heaviest:Once I get my "dot" I'll do some comparative trigger pull weight measurements. My guess -- and this is pure speculation on my part -- is that the "dot" may be in response to the increase in trigger pull weight brought about by the trigger bar used in the 4th gen guns.
- super secret minus-minus connector; I've tried one on another shooter's gun but don't have one myself (insert crying noises here)
- minus connector; the connector formerly known as the 3.5 and now technically the 4.5
- new "dot" connector
- standard
- "plus" connector; also known as the connector absolutely no one uses
