Knock-off Quality

I did not have success with a single part in this kit "as is." As a number of other reviewers noted, the guide rod assembly is so underpowered it allows gross movement of the slide wile pulling the trigger, so much so that the barrel would actually start to tilt and come out of battery leading to unsafe firing mode. Compounding this, the firing pin, guide, and cups are oversized and bind in every slide I've tried them in, at least this can be ground down to improve function, but entirely disappointing for a gun model that is not supposed to be custom fit like a bespoke 1911.

poor quality

Wish I had read more reviews before purchase. Recoil spring is very weak, extractor required fitting and back plate was very tight. I will replace all these parts as better ones become available. That this kit is available is about the best I can say for it.

Avoid this

The recoil spring in this kit is absolute garbage. It's so light my whole slide moves backwards when you press the trigger. I can legitimately compress the whole spring down to the base with 2 fingers and no effort whatsoever. Not to mention it looks like it was made in a cave with primitive tools
