Glad to help. Further info on connector markings (for Glock OEM) - the common ones are:

"+" (heavy)
no mark (standard weight)
"." (reduced weight, stock in gen 4 guns)
"-" (lightest, stock in G34, G35, G17L, and G24 iirc)

These marks are stamped into the connector and can be seen with the slide removed from the gun; the markings are on the inner face of the little bent ear that sticks up vertically from the connector (that ear is the reset leg btw.)

Also - gen 4 guns typically need one step lighter connector than gen 3 to achieve the same trigger pull weight. This is because of the difference in the ejector housing (Glock calls it a trigger housing) and the changes that were made to make the gen 4 grip smaller. Again, there are plenty of exceptions, but that is why the "." connector is standard in the gen 4.
