My agency still had us carrying the Model 10 as late as 1992. Man, now I think I'm going to have to buy one.
The top two are forged and the rest MIM.Before I lead everyone astray not all MIM parts get HIP'ed, in fact only a modest percentage does. But that process exists and the new generation of engineers that have "grown-up" with MIM know when that extra process/cost is needed and when less costly MIM processes are sufficient. And the powdered metallurgy (the raw metal injected into the molds) has come so far in the last two decades that the material properties of the resulting parts are far more dependent on the alloy chosen than the MIM process.
As for aesthetics I would offer this picture:

Can you pick out the MIM triggers and hammers? I can but it takes a close look and some research on my part to know for sure which was which.
I like all of these revolver and they have all been used a lot, some a whole lot in competition. I can proudly tell interesting stories of hunting and competition about all of them. The fact that some of them have forged parts and some MIM parts never crosses my mind except when I run across these threads. Of all these revolvers the one with the best single action and double action trigger (by a fair margin) is one of the ones with a MIM Trigger and Hammer. In single action that MIM trigger/hammer is better than than basically all of my other firearms including a Rem 700 with a fairly high end Timney trigger in it.
The top two are forged and the rest MIM.
To be fair, the hammer-mounted firing pins are a giveaway.
