So CDNN had a decent sale running on a few items and I picked up one of these at the same time:

Markings on the Sig parts the bag are:
1702287-R
Trigger assy, Euro
Made in United States
1507141003

Can I use this with a milspec Hammer and Disconnector?

What's the point of the hinging tip?

What did Sig put these in originally?

Looks like it would lengthen the reset.

For what it's worth, the hinged tip floats, without a spring. Not sure how it interacts with the components to reset.

It would have no effect on trigger pull if you look at the range of articulation.  It would hinge when the trigger was resetting and engage later than a standard trigger.  Perhaps the weenies in Europe no like a short reset?

I remember testing these. For the life of me, I can't really remember what they were for.

ETA: Right as I hit submit, I think I remember. I believe they were part of a 516 F/A fire control group that allowed the gun to go on safe with the hammer down.

Ah, that makes sense.

I became the Guinea pig on this.

The "hinged tip" does not float. The standard trigger spring applies upward tension to hold it up to engage the hammer.

I installed the "SIG Sauer Euro" trigger into a test fixture with standard GI FCG parts.

It functions like a standard Mil Spec FCG EXCEPT... you can, in fact, engage the safety while the hammer is cocked AND engage the safety with the hammer in the fired position!

Thanks for test fitting. I've got a LaRue Trigger jig I was going to do the same thing with but just haven't had time.  Makes sense now that you describe the hammer springs interaction with the floating tip.

Kind of an odd ball modification but I'd assume some major buyer asked for it so Sig accommodated the request.
