One of my friends is a Forest Service l.e.o. His higher ups have been pressing him to swap his Sig for a Glock due to some alleged frame rail cracking. He'd much prefer to keep his P226, especially in light of some well documented (ahem) kB issues. He's got about 10K through his piece with no visible defects. Any relevant info appreciated.

I think it has been pretty well documented that sometimes small crack have been seen in SIG frame rails- not limited to the 226 but I am not aware of a case where the cracking did anything to disable the pistol. In other words guns with cracks continue to work. Glocks that come unglued generally don't.

Are the cracks related to the amount of use, caliber or anything in particular?

I think use is the major factor but not all develop cracks. It's much more of a "this might happen" sort of thing, but even if it does it's not much of a big deal. I've seen dozens of 1911s with cracks but not one that quit working because of it.

In other words let us not make mountains...

The mid 80s P226s w the "scalloped" frame rails do it more than the older or newer guns, but as Charlie said, they all seem to keep working for some time when they do it. Point of impact/reliability might change a bit, or not. Some never notice the cracks until they look real close.

SIG added some cut outs in the frame rails (and some other mods) in the mid 80s for the M9 trials thinking it would improve reliability. Guns were more reliable than P226s in earlier M9 trials, but not as durable (two test guns cracked frames around 6-7K rounds, earlier guns did not). Jim Pledger, retired FBI/FTU told me it wasn't unusual for FBI SIGs to crack frames during an agents first 5K rounds in training (he worked for Glock then, wonder if he still mentions that now that he works for SIG?). SIG dropped that rail modification and the rails hold up much better much longer, like they did before. Hasn't been a problem for some time, but there are a lot of the older guns out there getting older, so the issue keeps popping up.

If it ain't broke, don't fix it? ;)

Another thing... SIG recommends replacing the slide roll pins in the older guns every 5K rounds, or w new pins if you take them out earlier for some reason (don't re-use them, replace them). If you don't, they can loosen and cause the breech block to stress the slide/frame in a way that may lead to cracks, according to Todd Green, SIG's Govt and Mil Project Mgr (formerly of Beretta USA). That and scalloped frames in older guns may have been what caused the cracks in 52 of Baltimore County's 1300 P226s a few yrs back... RTFM? :)

Problem pix needed

MikeO, Charlie Petty, or whomever:

Are there any photos or detail drawings available, so that we Sigophiles can examine our weapons to see if cracks have developed, or if they have the rail design that is reputed to be more likely to crack than other designs?

Photos would be nice, and detailed drawings might be better.

None of mine have cracked and I can't draw. Besides, I think it's sorta like pornography... you'll know it when you see it. :D
