If you mean the lint everywhere then I would say yes. Mine is always full of lint and dust when I clean it. If you mean the crack where the serial number plate is molded into the frame I would say no. Mine doesn't have a crack right there at least.

Well I wasn't talking about the crack. That has been there for awhile now. I sent this Sigma to S&W 2 years ago for a broken striker and the crack was there then. S&W never said anything about it. Guess i'll call them about it tomorrow. What I was talking about was the 2 dents on the frame.

Don't know how the crack happened. Haven't fired the gun in 2 years. What do you guys think is going to happen? I don't think they will give me an exact replacement model. S&W doesn't even make this model of Sigma anymore.

Did you buy the gun used? I would say the slide was locked back and the gun was dropped. The slide impacted the frame and left those dents. It would be easy to think that is how the frame was cracked. If you look at the bottom front of the dust cover then there should be an impact mark in the plastic somewhere to check my theory or debunk me.
I'll say your theory is plausible. I didn't notice the dents, my eyes went right to the crack. I'm really surprised that S&W didn't notice that. For sure, you should call them.

That actually might explain the dents, but that doesn't explain the crack. I don't see any dents on the dust cover.

I'd be more concerned about the impact areas on the frame, also the marks at the front of the dust cover....the impact area is where the slide is at when fully retracted....the possible rub marks out front are wonkish as well....the cracking is on the thin layer of plastic over the ID plate, and doesn't look of any concern, looks like the thin plastic is flaking off....but perhaps from flexing by whatever caused the denting to the frame?....I'd just send it back, and maybe get a new gun, unless you are having severe sentimental attachment to that particular discontinued (you said?) model...

That's what I was thinking about the "crack". Maybe just plastic flaking off. My concern was over the things you mentioned, denting in the frame and the rub marks. No sentimental attachment here, a new Sigma would make me very happy. I just prefer the all black Sigma's over the one's with stainless slide. If S&W says it's not a problem, then i'll just keep it and live with it.

I'd say something was out of spec, looking at the dents...if those are happening during cycling, the impact will eventually cause the frame to fail....i also wondered if something happened to the gun to cause the dents from impact/dropping/etc, either as a one-time deal, or if the rails got bent or something, now taking it out of spec and causing a problem during cycling.

It is a mystery. Funny thing is I never noticed those dents before and I never dropped this gun before. Maybe something happened at S&W 2 years ago?

I think this is why the rub marks are on the frame. This is normal right, are the frame and slide suppose to be that close to each other? Maybe the rub marks is normal wear and tear? It is a 13-14 year old gun.

You didn't even have to post the pic as i could already visualize what your gun was now doing....by way of comparison, my gun has the same amout of clearance up front as it does in back.....in your earlier pics, i don't see any sign of gross rail wear that would account for that much drop at the front of the slide...i would have to squeeze dust cover and slide together to get that contact you have going on....i don't see deformation of the rails in the pics, but they might have gottem squashed down somehow, maybe even someone else you allowed to use the gun, or perhaps it was played with unknown to you and something happened?.....who knows?....it surely ain't right now, for sure.....and might be a failure of material of workmanship instead of wear, and might net you a new gun, maybe even might have a spare Allied Forces black slide laying about up there at S&W......

I have noticed pretty much all of the first gen Sigma's look just like mine. With the really close slide and frame at the front. I am slightly squeezing the two together in that picture. Not very hard though. It still can't be good if it's rubbing. Anyway I got a email back from S&W. They sent me the link to fill out the warranty repair form. It takes 1-3 business days to get the shipping label through email.
Well, again, i'm more concerned about what's going on with the slide denting the frame under recoil, if that's what happened....the molds for the frames are very expensive, i've heard $100,000+ each, and i'd guess they have more than one....i look at some of the new SD complaints with the dust cover under the barrel off-center, which is only a cosmetic issue so long as things are running right, which is all the factory cares about, as far as their specs go and as far as their warranty goes...but likely not all SDs have the "fault", so it would lead to the assumption more than one mold or that the master wasn't faulty to begin with.....long way of saying it might be the same for your gun....it will be interesting to hear what they say when you send it back....they might replace the frame-only, replace the gun entirely, or tell you it's not a problem until and if it cracks...

It's all weird to me. I'm just waiting for S&W to send me that shipping label, so I can sent it off to them.
Just so you don't feel like the Lone Stranger, Glocks are also known for cracking at the SN plate, and the Sigma is considerably beefier there, which is why i think they made it that way....Glock slides also crack on the part that compresses the recoil spring, and i believe the Sigma is thicker there, as well....the AD issue was also know, hence the heavier trigger....the gun was supposed to be an improvement, and aside from QC issues or insufficient (2yr from concept to production) R&D, i think they succeeded....which is why i am amused by Sigma detractors...in it's mature design, it is a VERY good gun, and shoots as well as anyone else's.....Glock SN 200-ish was tested back when and scored just under 250 on an ISU 25m slowfire target by an accomplished competitor....you and i KNOW your Sigma can do that easily....a 250 basically looks like an even distribution of shots in each ring from 10 ring out to 7 ring, with maybe one X....send it back and see what they say, and i look forward to hearing what that is, as it might apply to me one day?
