Yeah, for the most part, if I were carrying three handguns on my person, it was a full sized sidearm, (Smith 1076 or Glock 35) and then the Glock 27 in an ankle holster. Then I usually had one of the NAA revolvers in my left hand pants pocket.
I figured the NAA about as good as a sharp knife in a worst case/last ditch scenario.
Very few folks ever knew I had it, as it was verboten to carry any unauthorized weapons on duty. I made sure to purchase mine where I had to fill out a 4473 on it, so I couldn't be accused of carrying a drop gun.
When the P-32 came out, I was just getting to the end of my road time, but I did replace my NAA with one of them for the last few months of my time on the road.
