I have read the same thing. I was looking to get an additional 19 receiver to cut down to 26 length. They don't sell them outright, but they do swap them.Call Glock. They will swap you frames for a fee, but IIRC it will not have the same numbers (but I THINK you can request it and wait a little longer for it to be stamped your original but "-1" or something similar added.) Give the boys down in Smyrna a call, they're real nice and usually do everything they can to help you out.
