"I have handled older SIGs. There is something about them that feels like it is higher quality. I am not sure how to measure something like that. To go along the lines of your argument though, if older SIGs had as many problems why aren't all those people appearing now and saying as much?"
I have more than a few of newer and older. Personally I have not noticed any difference in quality by handling them. However take my 1996 German P226 as an example. It does give me the warm fuzzies that it did come with original signed test target, has German proof marks, and triple serial numbers. Unless you get a Walther I don't know of any current manufacturer that does that anymore unless you buy a German made SIG and even not all them come with test targets anymore though I am pretty sure the X-5s still do.
The "older" SIGs had problems for sure. Early P226s had issues with frame rails cracking but that has been long ago been taken care of. Many have complained about rust issues with the folded carbon steel slide SIGs where the current stainless steel slide SIG pistols are much more resistant to rust.
The older German proofed SIGs also had no MIM parts I believe also. New SIGs, as do pistols from ALL manufactures, currently do. I am not trying to start a debate about MIM because it is here to stay and done correctly is not a problem. However given the choice I prefer my SIGs or any pistols to not have/minimum amount MIM parts and that includes Glocks and is one reason I will never get rid of my Gen 2 Glock 19.
I own and appreciate newer and older SIGs and love them all and for me they are my pistol manufacturer of choice. They each have characteristics that can make one more desirable over the other but they ALL have been 100 percent reliable for me and always bring a smile to my face when I start shooting them and to me that is what it is all about.
BTW for those interested Top Gun Supply has a limited amount of German made/proofed/triple serial numbers P229s in 9MM with Ilaflon finish slides. These, according to Tom at TGS, were made in Germany for a contract that fell through and he bought the whole lot. I am considering one for myself. I did converse with Tom and these do NOT come with a test target for those who would be concerned about that.
