I have one. It is fun to blow stuff up with. Like the other poster said, it is reasonably accurate for a 45 caliber snubby. Admittedly, it is also large and awkward for a snubby. Mine is the version that shoots 3" magnum shells. IIRC, they hold six 32 caliber pellets. I prefer my 4" 357 for SD. However, at close range, say "across the room" distance, my opinion after shooting it a fair amount, is that it would be effective. Shooting 30 32 caliber pellets at someone within a few seconds would probably ruin their day.
