Neil:
Welcome to the Forum!
I, too, formerly carried a Colt Mustang .380 IWB, then changed to carrying a NAA Guardian .380 as a pocket pistol. When the R9 prototype was unveiled at SHOT 2002, I ordered one sight unseen. In May 2004, I took delivery of R9 No. 132, and it has been my "always gun" for the past four years. In my opinion, it is simply the finest pocket pistol yet produced. It came with blue carbon fiber grips which I have replaced with a pair of the new aluminum panels. Here it is, with its Hedley leather, in a shot taken a few minutes ago to commemorate four years of flawless service.
