I'm doing my best getting the word out on .32 NAA. It's kind of hopeless tho because until someone other than NAA makes a production pistol in the caliber, there's going to be no demand by the ammo industry to make ammo for it and anything involving a new or niche cartridge needs both to work.
The number one thing that would greatly help the .32 NAA is if reloading companies would make die sets for them on a semi regular basis and price them around $50 a set, not the $300 for a custom set.
This thread is more focused on duty size or full size pistols, and the .32 NAA would be great in a longer barrel, but where it excels the most is LCP sized pistols and for me, I'm not a person who is putting 500 rds thru my LCP every year, maybe 200 a year because when I bring the LCP to the range, I only put 4 mags thru it at a time as any more than that it hurts too much. Thus, my point is I don't care if .32 NAA were to cost $20 a box, I'm not shooting so much of it that the extra cost of it over .380 makes it unaffordable.
For larger pistols where people are shooting 200 rds in an hour, they won't even entertain the thought of an ammo that costs 40 cents a round that's not as simple as 9mm is to reload.
