I really need to take photos, I could see the genealogy, but sure looked weird. I don't know the guy though. He had full auto trigger groups for AK's and that made me feel strange too. It may technically be legal when kept apart but gives me the creeps.
I have CNC produced 416 stainless triggers to replace the plastic triggers on Colt Mustangs, Mustang Plus II's, MK IV Government .380's and Sig P-238's. Video on installation in Sig;http://www.youtube.com/watch?v=Jh2v_-87DRM
Plus Llama .32 and .380 recoil spring buttons, checkered nicely and blued.
