Thanks for the help everybody. The PMR is awesome, just out of my price range. Personally, I like the RMR concept quite a bit more, too bad it's not in production.
In realistic terms, I may be over-estimating my needs. Having given it some consideration, I've settled on an NAA Mini 22lr and a Rossi 410/22 youth combo single shot. Total price is less than the MPA and both are available locally.
The Rossi swings and points very well with the 410 20" barrel, very light, and with practice and a side saddle, would make a decent HD weapon. The 22 barrel, while shorter, is quite front heavy, but still weighs in at ~4lbs, with cb longs, would make a great, quiet, squirrel dropper in the case of SHTF.
And the NAA Mini would make a decent, albeit diminutive, car/concealed weapon, should that need ever arise. Plus it's cool as **** and it's cheap.
Sorry for de-railing my own thread, but it seems I caught the tacticool bug for a minute there.
