Heat treatment for strengthening?

I think I may be getting a NIB EAA Witness Elite Match 10mm for Christmas, and have thus been researching them over on 10mmTalk. I have read a couple on instances of Witness frames cracking, and have had personal experience with an early version Witness .45 (1992-ish vintage) behaving badly.

My question is this: is there a heat treatment (or a cryogenic treatment, for that matter) that will demonstrably increase frame strength? I want to go with a through-and-through treatment, rather than a plating.

Thanks for any help!

I have not heard of any aftermarket heat treating of finished guns; barring a few places that do Mauser actions as another way of throwing money at army surplus.

So I take it you're recommending AGAINST the mauser-action thing? :)

I'm with JimW on that.

Where you at?
Get ahold of a heat treater and find out?

It's just a matter of figuring out (for sure!) what steel it is, then deciding on a heat treatment. They will know what can and can't be done. You might have to draw up some legal papers? ;)

If it's 4140 or 4340 the frame might be reheat treated to form Bainite.

BTW forget about the "cryo crap" ok? ;)

A cold treatment before the first temper has legitamacy the other ones haven't been proven, so looked upon by metallurgist as hype and jive.

Texas, DFW area.

I guess I'll either have to wait and look at the thing when I get it OR contact EAA... which sounds dicey considering their customer service rep. Maybe a local gunsmith can tell me...

If you are to get a proper heat treat, you need to know the alloy. Tanfoglio's website is uninformative on that, some makers brag about their steel, but not them that I can find. EAA? Yuk.

Just beat it to death and frame the wreckage as a memento.

I would put a buffer in it and try to kill it, if I was able to kill it I would consider myself fortunate to have the time and money to have been able to do it and look for my next 'victim'.

I really don't mind shooting guns until they need repaired or replaced, I hope and pray that many many more might meet their demise in my hands.

If you manage to kill it have the frame welded and kill it again. :)

You can have the metal analyzed to find out what it is.
