FCU once assembled fits fine in compact and full size frames but is incredibly right on the subcompact and requires you push the disconnect bar back in place because it’s so tight when you rotate the take down level. But over all it works great and has been reliable for 300 rounds so far.

Flawless. On par with- if not better performance than factory Sig FCU parts. Will definitely buy from them again and recommend this kit to anyone!

This LPK isn’t Sig OEM, it’s made by Patmos Arms. I wish they would’ve been more clear about this instead of just stating that this “LPK is an upgraded kit with new drop-safe components” which I mistook as Sig OEM Post-Recall LPK with the flat trigger instead of the curved one. I only mention this because I was specifically looking for a Sig OEM LPK, I wouldn’t have bought this had I known about it.

The quality of the parts and manufacturing is great, there are no burrs, sharp edges or defects. The finishing is good and are either polished, nitrided, or phosphated. The phosphated parts are the trigger, slide catch/release, and takedown safety lever. The trigger has the enhanced geometry of the Legion X5 Skeletonized flat trigger but just without the skeletonizing. The trigger geometry is the “upgrade” in this LPK. I’m pretty sure that the parts are MIM, but I cannot verify this. While this may not be Sig OEM, it’s a great quality LPK but only time and more rounds will truly indicate its quality.
