i like the mossberg 500 series. i would avoid a psitol grip stock because of the safety though. i'm replacing my knoxx pg with a regular shoulder stock.

i also like the look and feel of the mossberg 590 and 930. ive been looking at the jerry miculek 930 and it looks like a good option for a semi auto. nit sure if/when I will get around to getting another shotgun but a 590 or 930 is likely what i'd get.
