Okay. I ended up finding the one with the adj. sights I wanted instead, so I ended up selling the other one. They are basically identical, save the sights, and the one I sold was in much better cosmetic condition and had been fired much less. But this "new" one also came with the sought after stainless guide rod with the small spring loaded recoil reducer in the rear.
I called Smith and Wesson and talked to their guys. They wouldn't change the decocker to a safety only, and I they wouldn't disable the mag safety either. The job they do is to stone the sear and a small part on the hammer, and then to change the springs with Wolff springs. So I just broke out the Arkansas stone and a Dremel with a cotton drum and had at it. I disabled the mag safety by removing the plunger, and went ahead and kept the decocker. I changed my mind on that --nyresq is right there. Besides, my trigger job yielded a DA trigger smooth enough to negate the reason I wanted to disable the decocker anyway.
So after I got done, I got a much crisper release, very positive in SA, and the DA pull is a little smoother. I got the spring kits, but so far have been conservative on the weights I changed. I'll work 'em low one at a time until I find the point they fail, then go up a couple weights to be safe and get it reliable. At the point I have a -2lb. hammer spring, a +5% firing pin spring, a 22lb. recoil spring, and a 3.5lb. return spring. Feels good, but we'll see. I'll try lower weights to find the "bottom" as it were, but these springs are either just above factory weight or just below factory weight. They really made a difference though, that is for sure.
Anyway, after reading what I did and learning what they do, I figure I have a very similar trigger job to what they'd do, the Performance Center. They don't smooth out any of the roughness, but I may get around to that later --had they done that, it may have been worth it. It shouldn't be too difficult, but I need to get a bottle of machinists blue before I do it. I like detail work like that though, and I have a few other projects like this that require it.
Overall, I'm very impressed with the pistol and the outcome I got from tuning and tweaking it. It is better than it was, I'd say it is on par with a Beretta trigger to be honest, which isn't bad considering. I'm satisfied now. All I need are the Trijicon adj. inserts and sights and later I'd like to refinish it, but overall she's ready to go I believe.
I also ordered a Milt Sparks holster for it. I'll get that in June I think. I may look out for one of the Sig style decocker compacts next, the 1036? I saw one next to the one I bought, but it had magna-ports in it next to the sights. Did these come from the factory with magna-porting, anyone know? Does it affect the price?
