I have a Springfield Defender slide and barrel fitted to a Fusion arms frame. The upper half was built by the springfield custom shop in the late 80's or early 90's. I had the slide and barrel assembly and sent it to Fusion to be fitted to a carbon frame with chainlink front strap treatment. I used all the best parts from there.

Greider medium solid trigger

I am sure I am forgetting something. I have the receipts from Fusion for the frame and small parts fitting. I have only fired one box of bullets throught it since getting it back. The only thing left to do is the final finish. I was going to do a hard chrome frame and blued slide. I have a little over $1600 in it. I need $1200 out of it or may trade for Glass.
