I am no Smith Scholar but I have bought dozens of them over the past few decades and paid attention....
The original Stainless guns did indeed have stainless hammers and triggers.
My old model 66 is like that.
There was a problem when the guns heated up on firing, so S&W started putting on forged hammers and triggers that had been hard chromed. My first 629 was like that. Good gun.So was my model 686. It was a smooth, smooth gun, but did not stand up well to thousands of magnum rounds and got loose fast. (Never had that problem with the L frame).
Later, they added the internal endurance package and that is when my second 629 came about. Still a good gun. Well made too. Noticably less smooth though as handfitting was phased out for tighter computer numerically controlled machining procesess in manufacturing requiring less fitting.
This was also about the time that the mirror bright finish on blued smiths went the way of common sense in Washington....
Years later, I bought a stainless mountain gun and was dissapointed to notice that it had a case hardend hammer and trigger. To me, this made no sense. Why make a stainless gun for weather and corrossion resistance and leave the hammer and trigger prone to rusting? If you have been around as long as I have, you have encountered nickeled Smiths that have their internals rusted up. I saw a lot of those over the years by folks who thought "it won't rust" not realizing that only the frame, cylinder and barrell were plated. Other than that, it was still a good gun.
My second Mountain gun had whatappeared to be a case hardened hammer and trigger that were indeed investment cast (by the way, no matter what the companies want to call it--- MIM -kimber and smith- or Sintered metal- Colt, it's ALL investment casting or 'lost wax casting' as it was called about 2000 years ago. Ask a machinist or metallurgist. If it involves a mold and heated steel, it is a form of investment casting, no matter what the manufacturer claims to the contrary.
Old timers remember Colt's "sintered metal" claims from the Trooper era. Back then, they claimed that by heating up slivers of steel and pressing it into a mold it was "sintered metal" instead of Investment cast. MIM, Sintered Metal, no matter what you call investment casting, its inferior for some purposes, such as lockwork simply because there is going to be some porosity factors you just won't have with milled or machned forged parts.
Its a manufacturing short cut no matter what terminology the manufacturer prefers, and its to make a part closer to tolerance faster than it can be made by properly forging it and machining it to shape.)
My 'new' gun also had the frame mounted firing pin, which as an old fart, I don't care for on Smiths either.
My 629 snub had those and that ugly frame bolster too.
Shortly after that time, Smith introduced another indignity upon their wheelgun line - the key lock on the frame ---which required them to rescale that shapely scallop between the recoil plate and the grip frame as an ugly hump —and I started shopping around for used models instead of new ones. Better looking, less manufacturing shortcuts and easier on the wallet.
Now they have the two peice barrells and I have lost all interest in owning a "new" S&W.
What if you decide you want a three inch 686 like the one you saw Cylinder and Slide make a few years back in one of the gun magazines?
With the older style barrell, it was no big deal. Now the two peice barrell will be a pain in the butt.
I am wondering if the discontinuance of the K frame 19/66/65 series has to do with the fact that the key lock is prone to failure, not some inherent problem with the gun that nobody ever noticed before?
The only new Smiths I have seen in years I was interested in were the three inch model 66 with high viz sights (always regretted not getting one) and the TR Special .44. and some of the Heritage series guns.
Just because butt head politicians in Massachusets and California have lost their freaking minds with PCMania runnin' wild is no reason us gun fanciers should suffer while companies pander to those sleazebags who are trying to put them out of business. In fact, they should pander to hardworking Americans like you and me who have kept them IN BUSINESS for years when their own stupidity often nearly did them in.
