Maybe I misheard, but I understand he meant to imply the application of the HC wasn’t perfect. Or the metal, it’s prep, or it’s post-application handling we’re substandard.
I didn’t look research it when he said it, but a quick googling says that embrittlement can happen during electroplating, and cracks from when stress is applied to the part. I press fairly hard on the safety, so I can imagine I contributed to the crack
A engraved custom 9mm Colt. Some of the work done:
-standard Kart 9mm NM barrel, egw bushing and slide stop, re-shaped

My buddy Wayne has a 50s det special from a dead family member that he just got. It's really nice. I hate being envious but it's perfect. I meant to deliver some of my HST reloads but forgot.

I've been looking for a blued Super for probably 15 years now. Had a stainless one, currently have a Competition Model 1 of 100 in stainless as well (mainly the difference is the front strap is checkered and it came with a match barrel, otherwise it's identical to a standard stainless Competition model)...and finally found a blued Gov't model. For about the same price as it sold for new in 2013, at that. It sat in someone's safe for about 10 years; still coated in dried Colt gunk all over, no carbon anywhere.
