My understanding from Allem's Guncraft is that the triggers are different enough that Allem cannot put his new style release system in a 687. If you want the best release for a 680 series gun, you need to stay away from the 687. If you shoot pull, then the 687 would be the way to go since usually less expensive.
Replaceable barrel shoulders. That's what they are called by gun manufacturers.

"Details that make a difference
Triggers on all 682 E’s are adjustable for length of pull fit to three positions to better fit the gun to the shooter’s hand and shooting style. Two trigger shoes are supplied: one with a canted surface for right-or left-handed shooters and one with a wide, symmetrical face. Trigger pull is precise and lock times assured through the use of powerful core springs and sturdy alloy firing pins. Exceptional durability is ensured by self-adjusting , dual conical locking lugs, replaceable hinge pins and barrel shoulders, hard chrome-lined barrels and chambers, and obviously thanks to the quality of raw materials, the precision of machining and the perfection of heat and surface treatment. A newly designed ABS hard case, featuring the exclusive double handle, is included."

" Dear Greg,
At 9,000 OR 10,000 rounds per year, you aren't going to wear out two
686 Berettas in your lifetime. I currently own a couple of Berettas
O/Us (a 687 28 gauge and an Essential el cheapo field gun that shoots
far better than it should). I've owned 680s and 682s as well as other
686/7 models. Still, for Beretta knowledge I go directly to Rich Cole
of www.colegun.com. He is THE Beretta guy. You can take what he says
as gospel. As a writer, I simply parrot the opinions of my betters
Rich will be able to tell you exactly what the other (other than the
shoulders) differences are between the 682 and 686 competition models.
My guess is that the 682 has a slightly heavier receiver, but that it
only a guess. I'll tell you what isn't different- the insides. All the
682~6/7 series Berettas have interchangeable interior actions. That's
from the 687EELL right down to my mud sucking Essential. Same stuff
inside. Wood, barrels, decoration, etc, are different, but not the
So what's left are those shoulders. I asked Rich about them one day
and he told me that he could count on the fingers of one hand the
number of times he's had to replace them. It is simply not an issue.
When the Beretta O/Us loosen up it's almost always the locking tongue
with the two cylindrical probes that gets replaced. Beretta even
stocks them in series with numbers indicting the size. When your
factory locking tongue goes, you get the #1 replacement (or some such)
and then on to #2 later and so it goes. Hinge trunions also almost
never need replacement, though that's a piece of cake.
Beretta did an interesting thing with it's barrels when it changed
from the Mobilchokes to the overbore Optima Bore chokes. In the 391
gas guns, the barrels got heavier, but in the O/Us they got lighter.
That's probably why you felt comfortable going from the old 30" bbls
to the new 32" Beretta Optima Bore bbls. Guerini and Rizzini also have
nicely balanced long bbls. Citori hasn't yet seen the light.
Bottom line: you got two great guns so fuggedaboudid and just enjoy
shooting them. I bet you can't wear them out. I double dare you.
By the way, two guns are a smart move. I've always "paired" my
competition guns whether they were Remington 1100s, Beretta 303s or FN
B25s. Guns, particularly gas guns, are like sheep. They know when
they're alone and they don't like it.
I Just bought one of the 687 Unsingle combos from Etchens. I absolutely love it. I asked when I bought it what the differences were. The special order 687's have the replacable barrel shoulders just like the 682. And Beretta has not changed the trigger on those guns. It is the same as the one in the 682, it just doesn't slide. Anyone that could do a release on the 682 should be able to do it on the 687. If you wanted the adj. trigger they will sell it to you, You just have to have some one else put it in for you. They actually do the adj. combs in shop also. You get metal hardware instead of the plastic stuff that Beretta started using. If you are looking to save a few bucks and were going to get a 682 call Etchens and get the 687. In my opinion it's a nicer looking gun too.
I agree, the above post talks about the shoulders on a 686, or perhaps a std 687, BUT the Etchen 687 utilizes 682 barrels. ( it is a hybrid 687)
Caution re Adj combs from Beretta for 682 Gold E, not sure about other factory comb models. If you were to loosen the comb set screws and try and remove them all the way out, you will crack the comb wood. these screws are fitted into the plastic cavity that fits over the post, and inset into the comb piece. The actual hole in the wood for the Allen wrench is smaller than the set screw, so if you try and back off the screw all the way out, it cracks the comb.
