Okay, I admit, that was a rant. But it was on-topic!
I'm not sure I can really pin down the apogee of the 3rd Gens, but I can say a few positive things. First is that if you are a 1-2-3rd Gen guy, then you cannot subscribe to any axiom where you categorically write off MIM. The S&W MIM used in 3rd Gens is just the most easily obvious night & day argument for MIM done right that absolutely delivers.
There is almost zero report of MIM-related failures in S&W 3rd Gen pistols... and I think we here that are hardcore and knee-deep in to these guns here in this forum would absolutely hear even scattered odd MIM failure stories if they existed.
To be clear, the internet is blasted with MIM hate and MIM failure stories in guns... but
not MIM failure in S&W 3rd Gens. My position is that the best MIM in firearms that's ever appeared in large scale is the MIM in S&W 3rd Gens. Fight me!
Next bit of love: S&W's first attempt at a "Value Line" pistol could be argued as a failure to truly save money, make more profit and take back some market share. I say this because S&W did it for less than two years with the 915 and 411 before they went back to the table and REALLY started cheapening things down with the 908, 909, 910 and 410 guns.
But this is where the win is and where my love is -- the 915 and 411 are FANTASTIC guns that look good and work great. The 411 is scarce but the 915 was produced by the truckload in that short window they actually made them. If you find either of these for reasonable money, please take my advice and BUY BUY BUY. These are great guns.
