KJW M1911 questions
 

I am looking at a KJW M1911 US version that I might buy off of one of my friends I was wondering if they are compatible with the upgrade kits for WE or TM and the full metal ones from nova/ Springfield (it has the orange tip I hate those)

The KJW 1911 is a ~99% accurate copy of the TM 1911. Can't remember what the 1% difference is, my gut says spring guide.
