Yes, this set of sights will work AR-AP-ADEECF-SG161.
No, the model that is compatible with Springfield Armory is only for the XD and XD-M firearms.
These sights, AR-AP-ADEECF-SG165, are compatible with the Sig P229. There will be a difference in zero distance based on the caliber though.
Much of this is determined by your caliber. For a 9mm the sights would be a #8 front/#8 rear. For a .40S&W it would be the #6 front/rear.
MPN: SG-161 is a #8/#8 set, which would be used on 9mm and 357 SIG chambered P226 models. MPN: SG-165 is a #6/#8 set, which would be used on 40 S&W chambered P226 models.
Yes, MPN: SG-165 should fit.
Ameriglo (as well as Trijicon and Meprolight) list no products for the Grand Power pistols.

The "born-on" date, is not available. The products come in, and ship out with very little time in between, we don't have stock lying around from 2010.
The radioactive half-life of tritium is 12.3 years. In 12.3 years, they will be half as bright as when new.
