I know that a lot of different factors go into determining how durable steel will be, including metal composition, cast versus forged, and heat treating. What about high end customs where they weld up and re-cut the rails? Where do they fall on the scale?

My guess would be:

Unless the whole thing is post weld heat treated and stress relieved it's probably going to crack out at some point.

More than likely a whole lot faster than a non-molested frame.

But that's just my guess. A 1911 frame's rails are probably under very little stress and even if the metal's integrity is compromised, it may last for a long time.

I've worked around welding, machining and maintaining equipment and I can tell you that when it comes to metal: fatigue+welding+machining+more fatigue=a P.O.S.

That's why I just kinda wonder about those $7K customs built on a welded up rattle trap Colt.
