P320 Sear Housing

Trying to put together a P320 FCU. The only part I am missing is the sear housing unit.
Found a Sig Sauer P320 Sear Housing, DE, cost is $46 in stock. The ones that are Out of stock or half the price. Just wondering are there different Sear housing units for the P320.

They all look the same to me in the pictures.

The physical difference of the DE housing is that it doesn’t feature the Bottom stabilizer that the trigger bar sits on. Why? I have no idea, but my P320 sub compact operated fine. Possibly even reducing trigger pull weight.

I do have a spare housing. If you’re interested, $40/shipped

A big difference is pre vs post upgrade.

Post upgrade has a channel the disconnector rides in. Pre upgrade does not.

Post upgrade:

In the first picture above you do not see the Safety Disconnector channel as in saudadeii's picture

The DE is not a Post Upgrade Sear Housing..so it depends on what kind of a build your are looking for.
I'm not sure that I would compromise my build and spend $45.90 for a Non Upgrade FCU Build only because it is "In Stock"...
When I can purchase an Upgraded Sear Housing for $16.98 to $27.72

* For the same $45.90 you can purchase the entire Sig Sear Assy. with all of the parts included.

It's hard to wait for a Part to become "In Stock"

For Post upgrade and Safety Disconnector these are the Sear's that you want:

My guess is it's there to ensure the trigger bar doesn't slip out from under the disconnector. My next guess is yours is pre recall, like mine. No disconnector therefore no "stabilizer". My final guess is the DE above means Germany since the description says Made in Germany.
