SIG aluminum frames are prone?

Nope.


I blast max 357 SIG loads through mine on a near daily basis with thousands of rounds through them and nothing. Ive never seen a cracked SiG frame.
 
Way back in the early to mid 80's some P226's reportedly suffered from cracked frames. They would have rather low serial number ranges. Something like 114xxx 118xxx, etc. I believe it was posted here or sigforum at one point in time. SIG did change the rail design and beefed up certain areas over the years so it wouldn't be a problem. I own an old P226 that falls into the problem serial # range and it's pushing almost 20k without any troubles. I'm told it either happens or it doesn't. Newer SIGS shouldn't be a problem at all with normal maintenance and spring changes.
 
The frame of my first P226 cracked along the right frame rail about 1½" from the rear of the front rail forward. IIRC, I had about 8,000-9,000 rounds through it. This was in the very early '90s. Sent the gun in to SIG and they sent me a new one. I've gotten 3 other P22Xs since and have not had any problems.

Serial number was U401397 (have no problems with divulging the S/N as it is at SIG).
 
I have not seen one "crack" per se, but I have seen three that have failed. The first one the take down lever hole in the fram streched out to an oval shape. The other two the mag releases failed to retain the magazines. In all three instances the factory returned the weapons untouched, stating that since the weapons had been refinished the frames were no longer within tolerance and thus, the failures.

Needless to say all three guns were retired. The owner of the first one no only carrys LB 1911s and the other only carrys Glock.

Just to clarify, this is not second hand info, I was on the range when all three failures happened.
 
hello

My friend called the other night and said his beloved 226 frame cracked along
the rail. I am waiting pics. It is an 80's date and had around 20,000 rnds thru. He bought a new one, and hung the old one up. That's alot of rounds. I don't worry about it cracking.
 
The new frames have been beefed up for .40/.357. Cracking should not be an issue.
If you get a 9mm, your frame is overbuilt, like a tank.
If you get a .40/.357, I would go with a stainless steel frame for soaking up the recoil.
 
ones with a LOT of rounds through them...perhaps...in the '80s there was a lot of TALK about frame rails cracking...specifically during the military trials for their "M9"...both SiG's P226 and Beretta's 92FS (F) had this "problem" which was caused by the Military trying to see how much they could abuse the pistols before failure...at some point they (the pistols) failed...but I have never seen or heard credible evidence of any frame rail failures except those with the really high shot counts or abuse...at SiG Armorer School we were told the SiGs (Classic SiG/Sauer...the P229 had just come out last time I attended) could still function with one rail sheared almost completely off...of course accuracy would suffer...:what: ...:D ...
As for not warrantying a pistol that has been refinished...I can understand this as refinishing (say in Electroless Nickle) can change the characteristics of the metal (frame) causing the metal to be more brittle...I am sure there are other things that can happen as well...I bet squawking about it loudly (but respectfully) would have gotten you a new pistol or at least a deal on another...I do remember some Customer Service issues in the old days too...especially if you wanted ANYTHING during Desert Storm...we were told that the "G" came in and cleaned SiGARMS out of everything...I guess I can stand a bit of inconveninece when I am not being shot at to let our Military have spare parts for their P226s/P228-M11s...
Just another perspective...

This thread makes me wanna lay down and take a nap...

As for Sigs... wasn't aware they had a problem with their frames. All the ones I've ever had anything to do with were just fine.

Matter of fact, Sig P220's are what the local PD uses, and I've not heard of the first problem. ( And I would have, since I have a brother that's an officer there...)

Also, I made a holster for the first P239 that ever showed up in my area... that was about 10 years ago. No problems reported with it either. (One of our jailers has it )
