So in reply to your statement, "so the answer is that a full size barrel will fit, and lock up correctly" my answer is it appears so in a static situation.
I'm considering a range trip today (depending on the weather) and if I go, I'll take my .357 compact along with my full size .357 and .40 barrels and try them both out. I'll let you know my results. How's that sound?
