In the past I had seen vague references to this, and had wondered if it was just a catalogue-listed item from the manufacturer which never really went into retail packaging, or much production, but I have finally found an image (a bad one) of the box for the Lawman RHT .45 GAP frangible with index number 53396. It seems that it has been in the Speer ATK law enforcement catalog for several years, but is only ever available as 1000rd cases, and essentially only to the sparse law enforcement customers who order it. The bullet is 140gr, and so it is different than the 155gr RHT frangible used in the .45acp. The image below however is of 3 boxes which were listed on Armslist over 1 year ago. I see a couple places online presently offering it for sale, (1000rd cases only) but those are just law-enforcement-only distributors who are listing the entire Winchester an/or Speer L.E. catalog stuff.
Has anyone ever seen any of these? As far as I know, this is the only production-scale .45 GAP which I don’t have.
