I have a moss 500 with a 28" barell.I wanted a dedicated HD shotgun.It was between a $550 persuader or a $220 maverick 88 security.I couldnt justify the extra $300+ for something that hopefully only gets used for range duty.....and nothing else.I've looked real closely at buying one of these. If you have the money, I'd step up just a bit and get a Mossberg 500.
Every mossy that I've tried out has that.Not a concern on my part.All the mossberg fore-ends have the wiggly looseness. They tried some rings on the mag tube to minimize this at one time. It seems more or a characteristic than a problem though.
My dad's Mossberg 500 (bought NIB in the mid '80s) has this forearm "wiggly looseness," as does my Maverick 88 which was bought NIB in the late '90s. Neither of us have ever had any issues whatsoever with either of our shotguns.All the mossberg fore-ends have the wiggly looseness. It seems more or a characteristic than a problem though.
