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.
CNC produced 416 stainless triggers to replace the plastic triggers on Colt Mustangs, Mustang Plus II's, MK IV Government .380's and Sig P238's and P938's. Plus Colt Mustang hardened 416 guide rods, and Llama .32 and .380 recoil spring buttons, checkered nicely and blued.
