The last time I ordered something was a rifle. They shipped it out 2 days after I purchased. I believe they have to overnight pistols. I would guess your ffl should receive it rather quickly. If they don't have your ffl on file you would just have your ffl email them their info.
So will the 12rd mags from the full size gun work in the compact? I don't care that they will stick out of the grip, but will they function? Has anyone tried this? I have a full size and a bunch of mags....wouldn't mind picking up the compact if the mags work.
