Just heard from CMP. They offered to switch my order from an HRA (that will take several more weeks to deliver) over to a Springfield they can ship in a day or two. I took them up on it.
Nice! Everyone I've heard of that's done that has been pleased. Apparently they're getting a few Springfields in the batch they're working through but not enough to advertise so are offering them this way to whoever happens to come up next on the list when they're ready. Lucky you!
