Colorado:

I don't want to speak for the man, but in other posts (email) he said the fit wasn't right for him. He wanted a better LOP, drop at the comb, etc.

But like I said, this is from memory of what I recall him posting, but I'll let him correct anything/everything on my post.

He also said that upon selling, he'd probably order another .577 from Butch, made specifically for him.
