Cracked 5906 frame?

I am in Canada and have two 5946's a 5906 and a 5904. One of the 5946's has a cracked frame in the same spot, and a friend has a 5906 (that I sold him years ago) with the same problem. The earliest 5946 did not have a heat treated frame, so it will crack. Smith is aware of the problem, and I would think the 5906 was a first gen and probably was not heat treated as well. Later versions are heat treated and do not have this problem. I am getting my 5946 tig welded and back in service soon, as Smith won't replace the frame except for original owners.
 
I can't imagine a cracked frame on a 5906 unless you took a sledge hammer to it. Mine is built like a tank, and so have been all the other ones I have seen and shot.

Oh gee, 2 more cracked frames, that makes 4, at least.:( Pretty soon they'll catch up to the reported IL failures.

I HAVE SEEN SEVERAL CRACKED FRAMES. STAINLESS AND ALLOY IN THE S&W 3RD GENERATION. 9MM, .40 & .45 ,EVERYONE OF THEM HAD A SINGLE THING IN COMMON. THE OWNERS HAD NEVER CHANGED THE RECOIL SPRING. WHY DO PEOPLE THINK THEY LAST FOREVER. IT WAS WRITTEN IN THE RECRUIT TRAINING MANUAL THAT ATTENTION NEEDED TO BE PLACED ON THE SPRING REPLACEMENT. OF BOTH THE RECOIL SPRING AND MAGAZINE SPRINGS.

YEARS OF SHOOTING WILL WEAKEN AND SHORTEN THE SPRING CAUSING THE FRAME TO TAKE THE BRUNT OF THE RECOIL ENERGY. THE METAL BECOMES WORK HARDENED, FATIGUES AND THAN FAILS.

THAT BEING SAID I HAVE SEEN CRACKED FRAMES ON SIGS, GLOCK'S (THEIR SLIDES CRACK ALSO), COLTS, BERETTA'S, ECT.

IN A GUN MAG A FEW YEARS AGO (20 OR MORE) I SAW THE BEST ADVISE I HAD EVER SEEN ABOUT RECOIL SPRINGS. IT STATED TO BUY AN EXTRA NEW RECOIL SPRING WITH EACH NEW GUN. EVERY TIME YOU CLEAN YOU PISTOL COMPARE THE NEW SPRING TO THE ONE BEING USED. WHEN THE USED SPRING IN USE IS 2 COILS SHORTER THAN THE NEW SPRING; REPLACE IT AND ORDER ANOTHER NEW SPRING. SOLID ADVISE
