I’m specifically asking about a Glock 27.
I just picked up a 9mm conversion barrel from a super member here on the forum. I also plan to change to a 9 mm extractor, ejector and spring loaded bearing. This pretty much duplicates a G26 with the exception of the slightly larger slide bore.
After these changes are made will I be able to swap back to the .40 barrel and shoot that round without issue? It’s well documented that when going 40-9 the barrel change is all that’s really required. Changing the additional parts just adds reliability should I choose to carry it with 9s. I can’t find anything going the other direction after swapping internals though. I know it won’t be as reliable in 40 anymore, I just want do some comparisons between the calibers and need to know if I should hold off swapping the ejector, etc.
Thanks in advance for any and all information, Brian
