BINARY TRIGGER ON ITS WAY...ADVICE?

[bellavite1]

Hopefully this is the right place for it...

Jut yesterday this guy comes in at work (Silverbullet) with a Sig MPX pistol.

The damn thing was equipped with a Franklin BFS III trigger, the binary that fires one round on pull and one on release.

At first I thought somebody's gun was doubling, so I offered my (limited) help.
When the guy told me it was a binary trigger I was quite unimpressed, I always considered it a novelty, kind of an expensive slide-fire deal.

He offered me to try it...
he said "just barely feather the trigger"...
the damn thing turned into the closest thing to real full auto I had the pleasure to experience since I sold my UZI SMG!

A normal trigger pull still gave a very quick double tap, but both me and my coworker were able to do full mag dumps in no time...

$325.00 later, I have one coming my way...
I like the 3 position selector that will give me familiarity with a real AR fun-switch, the fact that every thing else in the gun stays the same, the $325 vs $35000 price...
It comes with an extra power buffer spring that should minimize the chances of a hammer follow, and two set of FCG springs .
It will go on my 5.56 10.5" AR pistol, which I already set up with an SB tactical collapsible brace (ATF will have a fit with this thing by the time I am done ).
I am assuming that, to help minimizing the hammer follow, a regular carbine buffer would be the way to go.
Since I'd like to use Tula cheapo rounds in it (lots of them... ), maybe an extractor upgrade (BCM maybe) could also be worth getting.

Any current users care to chime in?
