I have purchased two new S&W revolvers in the past three years. A nickel Model 36 and a Model 64. Both have the IL and MIM parts but they're definitely old school hand guns.
My wife bought a new automatic (M&P 9C) last year.

I wonder how many people outside of this forum of hard-core collectors have even heard of "IL and "MIM"? Not too many, I'll bet. The general populace certainly doesn't and I'll further wager that whether the new models have or don't have these particular features amounts to "a mote in God's eye" in overall sales.

Come Sancho, time to saddle up Rocinante ...
