I’ve used Randy aka Sledgehammer multiple times. A GOOD, solid human being. He’s had some health issues a few years back, which meant he stepped back some, but all in all, he’s as good as the best, and better than most.
Gunplumber is also as solid as they get. Not a “people person” but he knows his shit. My issue for me is that I can drive to Randy’s in a couple hours, I gotta deal with UPS for GP. GP is usually backed up for months, especially with my junk, because I create replicas on original parts kits that I want perfect. That takes time and can be tedious.
He might be faster with generic builds.
