Surprised to see that Mossberg does the 12, 20 and .410 in their model 500, but not the 28 Gauge. A limited run of 28 and why not.........do some 16. Both can be done on 20 gauge frames.

Mossberg made a 500B (16 gauge) in the past. They've never made a 500D (28 gauge). And bite your tongue about combining frames. IIRC, Mossbergs always had gauge specific frame.

I own a 28 gauge Wingmaster, but I'd sure like to see Mossberg make a 28. I think that would be cool. I wouldn't hold my breath, though.

The slickest 28 gauge pump, in my opinion, is the Browning model 12.

The 500B was built on the 500A frame.

I just bought a Mossberg SA-28, 28 gauge semi-auto!
Lovely little gun, haven't had a chance to shoot it yet.
Comes in a nice hard plastic breakdown case.
5 choke tubes (mobilchoke) BUT it doesn't come with
the choke tube wrench! There is a spot molded in the
case about the shape that would hold a Beretta wrench,
but I can't find that in 28 gauge. I can find a 20 gauge wrench
in that shape, but not the 28 gauge. Any information on this
subject would be greatly appreciated!!
Thanks!

JJP. check behind the "trap door" underneath the top of choke tube case. Go Buckeyes!

JJP, sorry did not read your entire post. The key like wrench is supposed to be an universal wrench for all gauges. Mine took forever to change chokes so I bought a Briley speed wrench. Hope this helps.

Isn't the internet an AWESOME thing?!
It was right where you said it would be Lam101.
It is definitely the most generic wrench I've
ever seen, but it will work. Thanks!
Yeah definitely Go Buckeyes!

And if I was going to shoot sporting clays
and need to change chokes during the
round, I would definitely need a speed
wrench. I'll probably be using it only for
skeet & maybe a little bird hunting so it
shouldn't be an issue.
