Glock's ambitious 2003 attempt to fit .45 ACP performance into a shorter case that worked in a smaller grip. It was a clever engineering answer to a real problem and a handful of police departments bought in and then the whole thing quietly faded as pistol grips got better anyway. A footnote with a devoted little following.
Loads run 185 to 230 grain in a shrinking catalog. A genuinely fading caliber priced like the specialty item it became. Owners of the guns buy when they find it because tomorrow it might be gone.
