buy the pump action one 3 shots
Ive the mossberg 3 shot pump action hushpower .410. Its a nice gun, but extremely long with the silencer, due to the longer receiver which pump actions and semi`s have. Its also apparently not as quiet as the single shot versions, as the silencer is smaller. The other down side is that normally the mossberg one costs about twice that of the single shot, so its debatable as to how much more those 2 extra shots are worth.
depends on what your using it for really, bolting rabbits in close proximity to houses springs to mind.
