I have a pre-Model 10, which might be older than I am (65).
By & large, Smith revolver triggers have always been the high point of their design, IMO. Back-in-the-day, their single action pull was a joy to behold. Some models got at or below the 2lb mark, which is bullseye-level setting. Some would call that light trigger a "hair trigger" as well. Some would call it "just right".
Don't fear a good trigger on a carry gun! The fix is perfectly simple: don't cock the hammer! In a defensive situation leave the hammer down! That way it's a longer, double action pull, somewhere in the 8-9lb area, most likely. If you're holding someone for the cops at gun point, you certainly don't want a negligent discharge if the guy sneezes, for example.
Prior to about the mid-1960s or so, the Model 10 was arming the vast majority of America's police officers. The remaining went with a Colt model. The two guns looked different but operated the same for all intents & purposes.
The Model 10 allows a shooter to ease into using centerfire ammo without dealing with a lot of recoil. Using wadcutter-type ammo, it's not much more recoil than a .22LR gun. As the shooter gets more experience & comfortable, they can bump up the ammo loadings to where they're most confident with it.
Every gun owner should own some sort of .38sp steel-framed revolver, IMO. They're perfect nightstand guns, IMO.
While the wonderful police trade-in deals are now long gone, a used Model 10 can sometimes be had in the upper-$300s, lower $400s with a little shopping. They may not look as pretty as a new one, but they'll often outshoot the newer guns.
