The 66-4 was the last 66 to be MIM free. The 66-5 incorporated MIM. The 66-6 incorporated the zit. The 66-7 was the least desireable, having MIM, IL, and a two piece barrel. There were not many 66-7's before the 66 went away.
The 66-2, 66-3, 66-4 and 66-5 were all produced with 3" barrels. Hope this helps. Regards 18DAI.

Not entirely. While some on the forum have owned 66-4's they believed to be MIM free, myself and others have owned 66-4's that definitely have MIM parts. The 66-4 below (top gun) has a MIM hollow trigger. Hope this info helps some.

That's my opinion. I have found 3 M66 3inchers in the last year, a -2, -3, and -4. Only the -2 and -3 were non MIM, but that personally does not bother me. Some of my favorite S&W have MIM. Here are pics of the -3, then the -2, you've already seen the -4...
As to which one is better, you will be extremely lucky to find either one, so grab the first one you come across, would be my advise.

I have a 66-2 snubbie and a 66-6 PC 3" carry comp. The action on the -6 PC gun is so much smoother then the -2 (in spite of having an action job done on it) that it's hard to believe. As much as I hate the looks of the lock, the 66-6 is more enjoyable to shoot.
Ok, MY 3" 66-4, and the previous two 66-4's I owned, HAVE been totally MIM free. Forged hammers and triggers, no internal MIM parts.
Evidently, some 66-4's are not MIM free.
So in order to avoid MIM, examine any 66-4 carefully, or go with a -3. Regards 18DAI.

MIM stands for Metal Injected Molding. It is a process for making gun parts (as well as many other things) that is cheaper than making forged parts. Some consider them to be inferior to the forged parts. From what I have read, MIM is more likely to fail, but if it is going to fail it usually does it quickly. If it survives the first few thousand rounds it will usually last just as long as a forged part. Since my new found love for S&W revolvers is for the slightly older models, I prefer to find models prior to the use of MIM parts.

MIM I don't like but I can do. The locks, I can't do!
