I have an NAA Mini Master that used to be my right front pocket CCW (S&W 342PD now serves that purpose). I customized an Uncle Mike's .38 holster to make a pocket holster ideal for carrying the Mini Master - simply sewed a seam straight along the line of the seam that held the Uncle Mike's name tag - a perfect fit of gun to holster and holster in pocket.
The NAA Mini Master now stays loaded with snake shot for use against cottonmouth water moccasins and copperheads.
If I ever felt a need for a backup for the 342PD, I'd just put the NAA MM in the left front pocket, loaded with CCI Maxi-Mag Plus V's.
It is a fun gun, cheap to shoot (practice with a .22LR cylinder).
NAA service is excellent. I sent it back to the factory to have the trigger smoothed, and the result was perfection.
The Millet blaze orange front sight is very easy for my old eyes to see, especially in low light.
