Are they the same? I can't find anything that says either way? I mean, the length of pull/trigger to backstrap distance is shorter. So I am sort of assuming no, but I am not sure where Glock made the dimensional changes.
Ahh. So the trigger housing itself is different (the part that holds the ejector, connector and trigger spring)?
I am trying to come up with a parts list for a 21 long slide build on a 21sf frame and just want to make sure I don’t end up with something that is 21/20 compatible only and the part is different for a 21fs/20sf.
