The 556 has serious problems with rails, finish and fit.
Since I dont own one, all I can say is, of the half dozen or so I've personally handled, they all seemed to be well made, and well finished. I didnt notice that the rails were canted, not that I was really looking, but if they were, it wasnt obvious. Next time I run into my buddy, I'll have to see how he's making out and if things are any different.
The mosquito is a problem gun for Sig even today. .................. The P22 about on par with the Sig but costs about $100 less.
Just curious, but how many of either have you personally been through to know for a fact that this is the case? Besides myself, I know probably close to eight or ten people who have one or both and used to shoot with them on a fairly regular basis, and no one was complaining of all these so called problems. Usually when you see the threads bitching about them, when you weed out who owns them and who doesnt, the list of complainers goes down considerably.
As far as what they cost and who makes them, who cares? Where else can you find a gun that is similar to what you shoot big bore in small bore? I really didnt think the cost was all that bad for either. From what I've seen, they have actually come down some in price.
The same is the case with the P220 extractor. Its not one every now and then. There are so many documented cases of FTF right out the box on a regular basis. The concept that one should pay $800+ for a new Sig pistol and then find out if its a dog is absurd IMHO. The reason you are paying $800+ for a Sig is so you don't have to deal with that crap. It should not only be an issue after multiple returns. It is an issue right out of the box since they knew about the design problems before they shipped the guns.
Again, I have to ask, how many of the new so called problematic P220's do you or have you personally owned that were a problem? If so, was the problem addressed by SIG, or are they still a problem?
I've owned a number of guns guns from just about every major maker out there, and some have a lot more issues than others, but sooner or later,they ALL have an issue with something. When those issues start being continual, either because they were not fixed or successive guns were also a problem, then I dont buy them any more. If thats the case with you and SIG, then I'd move on.
All I can say for me is, I havent "personally" encountered any of the problems you keep bringing up with those guns that I actually own, so until I do, I'll be skeptical. Like I said, I've seen a lot of people who never owned and probably never even shot the guns they were bitching about and bad mouth them at every possible opportunity. If you personally have had issues that were not or cant be addressed, then you have a right to bitch, if not, you really have nothing useful to add.
As for all the crying over what SIG has changed that you dont like, you either have to get over it or move on. If they do in fact have issues with a couple of models, then I'm sure they are being addressed, and if they arent, dont buy them. Its as simple as that. My newer model SIG's, while ever so slightly different looks wise, have worked and shot just like my older model SIG's. when they stop doing that, I'll look for a maker that will accomadte me.
I've been there with a bunch of other makers before and some I lived with, because they changes were cosmetic, and didnt do anything to affect the guns working, and were easily enough remedied to my satisfaction, although they were annoying to me. Colts specifically were my issue, with their plastic parts on later guns, etc. The thing with the Colts was, they worked out of the box for the most part, just like SIG, old or new, and there were always the purist complainers going off about how far Colt had fallen. The bitch of it was, Springfields and Kimbers, no matter how fancy looking or supposedly impressive they were, they were not as reliable or shootable out of the box as the Colts.
Just because other companies are cheapening their product and lowering their standards does not mean all good companies should.
This is merely your personal opinion. Some may like where SIG,or any of the others have gone. They obviously have been trying to address what people seem to want, just by the number of new models they have been making (as well as some of the discontinued models), even if those things are not to your liking. Again, if you dont like it, just move on. Being bitter about it (and its pretty obvious by your posts your bitter about it), wont make you (or us) feel any better, unless of course, you like feeling that way. If so, by all means, carry on.
As for the P6 comment I assume that you know the difference between a P225 and a P6.
I know the difference. Both of my P6's have the P225's mainspring in them and they both now have a DA trigger that compares to all my other guns. Other than that, there is really little difference between them, at least functionally wise. But then again, theres the "purist" angle.....
As far as trigger reset, I still think thats a shooter issue and not a gun issue. Most all the "upgrades" people seem to "need" are usually the shooters problem or crutches and not the guns fault. Some things, like the P6's triggers do need addressing, but for the most part, if you cant shoot a gun as it comes out of the box, (unless its a defect) its usually not the guns fault.
Personally, I dont believe in messing with the basic function of the gun. Once you do, you pretty much always cause yourself problems down the road. You also become more hooked on the need for the crutches. They spend millions of dollars in R&D and tooling, but theres always someone out there with some sort of fix, who knows better, and probably wants to sell you something.
