1st gen a little iffy. 2nd gen reliable as any other S&W. Never had a problem with 'em (knock-on-wood). Wife's gun is a SW40F. Was a policewoman's gun. It's been put thru its paces and is darn reliable. The wife and I favor heavy revolver-like triggers. It gives consistency and is also a safety feature. No such thing as an inadvertent shot with one.
I have a number of the 2nd gens. They make great rainy day guns. Go-Home / Get-out Bags, NY reloads, trade/barter, arm every member of the family including the in-laws. . . I even got a SW357V - yup - a Sigma chambered in 357 SIG. As with any handgun, revolver or semi, they have to be put thru its paces. Issues will show in the first 250 to 500 rounds. If it's a lemon, it'll show itself.
Will they ever become collectible? Um....aside from MAYBE the SW357V, no way will they ever become collectibles! And this is coming from a fan.
My next Sigma will be a 3rd gen.
