I remember hearing how work on sears should be extremely conservative. Partially because the precise angles involved but also because warnings that sears were hardened on the outside only and soon you'd have push-off when worn down to soft steel. Does this apply to revolvers only, and only older revolvers at that? I assumed it was because there weren't any computer controlled processes / ovens like there are today so the easier way would just be to heat up a cheaper piece of steel and swish it around in a given media.
How about SA/DA semi autos? Like my Jericho 941F (made in the 90's) or my CZ 75 SP-01? Those sears are so small, wouldn't it be easy in a factory to heat, quench, then temper a huge tray full at a time? That way they'd be through-hardened.
Are sears still truly case hardened only? If so, why?
- by the way, I'm not planning on going nuts on my sear. But I did just purchase a beater SA/DA pistol, and if I was ever going to stone a sear it would be this one as Tanfoglio small frame / EAA witness fire control parts are compatible and plentiful.
